Secrets of the Priestly Blessing

This week’s parasha (in the diaspora) is Nasso, the longest in the Torah. In it, we read how God commanded Moses to instruct Aaron and his priestly descendants to bless the people with the following formula:

יְבָרֶכְךָ יְהוָה, וְיִשְׁמְרֶךָ. יָאֵר יְהוָה פָּנָיו אֵלֶיךָ, וִיחֻנֶּךָּ. יִשָּׂא יְהוָה פָּנָיו אֵלֶיךָ, וְיָשֵׂם לְךָ שָׁלוֹם

Loosely translated: “God bless you and protect you; God shine His Face upon you, and be gracious to you; God lift His Face upon you, and place peace upon you.” (Numbers 6:25-27) This unique, enigmatic phrase carries tremendous meaning, and an interesting history, too. In fact, the oldest Hebrew inscription of a Torah verse ever found is this blessing!

In 1979, archaeologists in Ketef Hinnom near the Old City of Jerusalem discovered two small silver scrolls. After painstakingly unravelling the fragile scrolls (a feat that took three years), they discovered that they were inscribed with Birkat Kohanim, the priestly blessing, along with a few introductory lines. The scrolls have been dated back to the 7th century BCE, and are considered among the greatest finds in the history of Biblical archaeology.

What secrets are buried within the words of Birkat Kohanim?

Restoring Divine Light

In introducing the Priestly Blessing, the Torah commands koh tevarkhu, (כֹּ֥ה תְבָרְכ֖וּ), “thus shall you bless…” The Zohar (III, 146a) reminds us that koh is an allusion to the divine light of Creation. The value of koh (כה) is 25, hinting to the 25th word of the Torah, “light”. When Adam and Eve consumed the Fruit, that original divine light of Creation was concealed. This is the secret behind God calling to Adam: ayekah (איכה), usually translated simply as “where are you?” but really meaning ayeh koh, “where is the divine light?” Indeed, the very purpose of the kohen is to help restore some of that hidden divine light. This is why he is called a kohen!

It is also why it is customary not to look directly at the kohanim when they relay the blessing. The hidden light may be far too intense, and might cause the observer’s eyes to dim (Chagigah 16a). The ancient mystical text Sefer haBahir (#124) adds that the kohanim put together their ten fingers in that unique arrangement in order to channel the energy of all Ten Sefirot. Elsewhere, we learn that the hands of the kohanim come together to roughly form an inner samekh, the only circular letter in the Hebrew alphabet, representing infinite cycles and endless blessings. Sefer haTemunah teaches that the proper shape of a samekh is a combination of a kaf and a vav. (The sum of the values of kaf and vav is 26, equal to the Tetragrammaton, God’s Ineffable Name.) Kaf literally means the “palm” of the hand, and the linear vav represents a shining ray of light.  These are the hidden rays of light, the light of koh, emerging through the hands of the kohanim as they bless.

In his commentary on the Torah, the Ba’al haTurim (Rabbi Yakov ben Asher, 1269-1340) states that koh reminds us also of the Akedah, when Abraham told his attendants that he and Isaac would go ‘ad koh, “until there”. The deeper meaning is that Abraham saw the divine light emanating from the top of Mt. Moriah, the future site of the Holy of Holies. This is how he knew exactly where to bind Isaac. Previously, God had already blessed Abraham with the words כה יהיה זרעך, that his offspring would be luminous (and numerous) like the stars (Genesis 15:5). The Ba’al haTurim adds that the Shema has 25 letters for the same reasons and, amazingly, the term “blessing” is mentioned 25 times in the Torah, as is the word “peace”!

The first line of Birkat Kohanim has three words and fifteen letters, the Ba’al haTurim points out, alluding to the three Patriarchs—Abraham, Isaac, and Jacob—whose lives overlapped for 15 years. Recall that Abraham had Isaac when he was 100 years old, and Isaac had Jacob at 60 years old, ie. when Abraham was 160. Since we know Abraham passed away at the age of 175, there were 15 years when all three Avot lived together.

More specifically, the first line of the blessing is for Abraham, the second is for Isaac, and the third is for Jacob. This is why the second line speaks of illumination since, as is well-known, Isaac saw the intensely bright divine light unfiltered at the Akedah, and this is the reason he later became (physically) blind. The Sforno (Rabbi Ovadia ben Yakov Sforno, 1475-1550) adds that within the second line of the blessing is a request for God to give light to our eyes so that we could see God within all things, in all the wonders of the world, and in all the wealth (material and otherwise) that God has blessed us with.

The Ba’al haTurim continues that the third line of Birkat Kohanim is for Jacob, which is why it begins with the word yisa (יִשָּׂ֨א), reminding us of Genesis 29:1 when Jacob fled (וישא יעקב רגליו). It has seven words to indicate the subsequent births of the Twelve Tribes, who were (except for Benjamin) born to Jacob over a span of 7 years. The last line again has 25 letters to remind us of koh, and further alludes to the Sinai Revelation—another burst of divine light—when God said (Exodus 19:3) “thus [koh] you shall speak to the House of Jacob” (כה תאמר לבית יעקב). The Ba’al haTurim concludes that the final word of the blessing, shalom, has the same numerical value as Esau (376) to teach us that one should spread peace among all people, gentiles included, and even Esau!

Ibn Ezra (Rabbi Abraham ben Meir ibn Ezra, 1089-1167) says that “peace” means complete peace, with not even a little stone or a wild animal to bother a person. Meanwhile, the Ramban (Rabbi Moshe ben Nachman, 1194-1270) says that “peace” here refers to shalom malkhut beit David, peace upon the kingdom of David and his dynasty. We may infer from this that it refers as well to geopolitical peace in Israel, and a request to hasten the coming of Mashiach. This is related to the Sforno’s interpretation, as he says the verse refers specifically to the World to Come in which, as described in the Talmud (Berakhot 17a), the righteous will bask peacefully in God’s glory.

May we merit to see it soon!

Time Travel in the Torah

This week’s parasha is Ki Tisa, in which we read of Moses’ return from Mt. Sinai where he had spent forty days with God. During that time, he had composed the first part of the Torah and received the Two Tablets. The Talmud (Menachot 29b) tells us of another incredible thing that happened:

…When Moses ascended on High, he found the Holy One, Blessed be He, sitting and tying crowns on the letters of the Torah. Moses said before God: “Master of the Universe, who is preventing You from giving the Torah [without these additions]?” God said to him: “There is a man who is destined to be born after many generations, and Akiva ben Yosef is his name. He is destined to derive from each and every tip of these crowns mounds upon mounds of halakhot.” [Moses] replied: “Master of the Universe, show him to me.” God said to him: “Return behind you.”

Moses went and sat at the end of the eighth row [in Rabbi Akiva’s classroom] and did not understand what they were saying. Moses’ strength waned, until [Rabbi Akiva] arrived at the discussion of one matter, and his students said to him: “My teacher, from where do you derive this?” [Rabbi Akiva] said to them: “It is an halakha transmitted to Moses from Sinai.” When Moses heard this, his mind was put at ease…

Up on Sinai, Moses saw a vision of God writing the Torah—this is how Moses himself composed the Torah, as he was shown what to inscribe by God—and he saw God adding the little tagim, the crowns that adorn certain Torah letters. Moses was puzzled by the crowns, and asked why there were necessary. God replied that in the future Rabbi Akiva would extract endless insights from these little crowns.

Moses then asked to see Rabbi Akiva, and was permitted to sit in on his class. Moses could not follow the discussion! In fact, the Talmud later says how Moses asked God: “You have such a great man, yet you choose to give the Torah through me?” At the end of the lesson, Rabbi Akiva’s students ask him where he got that particular law from, and he replied that it comes from Moses at Sinai. Moses was comforted to know that even what Rabbi Akiva would teach centuries later is based on the Torah that Moses would compose and deliver to Israel.

This amazing story is often told to affirm that all aspects of Torah, both Written and Oral, and those lessons extracted by the Sages and rabbis, stems from the Divine Revelation at Sinai, and from Moses’ own teachings. It is a central part of Judaism that everything is transmitted in a chain starting from Moses at Sinai, down through the prophets, to the Anshei Knesset HaGedolah, the “Men of the Great Assembly” and the earliest rabbis, all the way through to the present time.

What is usually not discussed about this story, though, is the deeper and far more perplexing notion that Moses travelled through time! The Talmud does not say that Moses saw a vision of Rabbi Akiva; it says that he literally went and sat in his classroom. He was there, sitting inconspicuously at the end of the eighth row. As a reminder, Moses received the Torah in the Hebrew year 2448 according to tradition, which is 3331 years ago. Rabbi Akiva, meanwhile, was killed during the Bar Kochva Revolt, 132-136 CE, less than 2000 years ago. How did Moses go 1400 years into the future?

Transcending Time and Space

In his commentary on Pirkei Avot (Magen Avot 5:21), Rabbi Shimon ben Tzemach Duran (1361-1444) explains:

Moshe Rabbeinu, peace be upon him, while standing on the mountain forty days and forty nights, from the great delight that he had learning Torah from the Mouth of the Great One, did not feel any movement, and time did not affect him at all.

As we read at the end of this week’s parasha, Moses “was there with God for forty days and forty nights; he ate no bread and drank no water, and He inscribed upon the tablets the words of the Covenant…” (Exodus 34:28) At Sinai, Moses had no need for any bodily functions. Rabbi Duran explains that from his Divine union with God, Moses transcended the physical realm. In such a God-like state, he was no longer subject to the limitations of time and space.

In this regard, Moses became like a photon of light. Modern physics has shown that light behaves in very strange ways, and does not appear to be subject to time and space. Fraser Cain of Universe Today explains how

From the perspective of a photon, there is no such thing as time. It’s emitted, and might exist for hundreds of trillions of years, but for the photon, there’s zero time elapsed between when it’s emitted and when it’s absorbed again. It doesn’t experience distance either.

Light transcends time and space. In this way, Moses was like light. And this is quite fitting, for this week’s parasha ends with the following (Exodus 34:29-33):

And it came to pass when Moses descended from Mount Sinai, and the Two Tablets of the Testimony were in Moses’ hand when he descended from the mountain, and Moses did not know that the skin of his face had become radiant while He had spoken with him. And Aaron and all the children of Israel saw Moses, and behold, the skin of his face had become radiant, and they were afraid to come near him… When Moses had finished speaking with them, he placed a covering over his face.

Moses glowed with a bright light, so much so that the people couldn’t look at him, and he would wear a mask over his face. Moses had become light. And light doesn’t experience time and space like we do. There is something divine about light. It therefore isn’t surprising that the Kabbalists referred to God as Or Ain Sof, “light without end”, an infinite light, or simply Ain Sof, the “Infinite One”. Beautifully, the gematria of Ain Sof (אין סוף) is 207, which is equal to light (אור)!

Travelling to the Future

While Moses was instantly teleported into the future, we currently have no scientifically viable way for doing so. However, the notion of travelling into the future is a regular fixture of modern science fiction, and the way it usually presents itself is through some form of “cryosleep”. This is when people are either frozen or placed into a state of deep sleep, or both, for a very long time (usually because they are flying to distant worlds many light years away), and are reanimated in the distant future. For this there is a good scientific foundation, as there are species of frogs in Siberia, for example, that are able to freeze themselves for the winter, and thaw in the spring. They can do this without compromising the integrity of their cellular structure, in a process not yet fully understood. If we could mimic this biological process, then humans, too, could potentially freeze themselves for long periods of time, “thawing” in the future. And this, too, has a precedent in the Talmud (Ta’anit 23a):

[Honi the Circle-Drawer] was throughout the whole of his life troubled about the meaning of the verse, “A song of ascents, when God brought back those that returned to Zion, we were like them that dream.” [Psalms 126:1] Is it possible for a man to dream continuously for seventy years? One day he was journeying on the road and he saw a man planting a carob tree. He asked him: “How long does it take [for this tree] to bear fruit?” The man replied: “Seventy years.” He then further asked him: “Are you certain that you will live another seventy years?” The man replied: “I found [ready-grown] carob trees in the world; as my forefathers planted these for me so I too plant these for my children.”

Honi sat down to have a meal and sleep overcame him. As he slept a rocky formation enclosed upon him which hid him from sight and he continued to sleep for seventy years. When he awoke he saw a man gathering the fruit of the carob tree and he asked him: “Are you the man who planted the tree?” The man replied: “I am his grandson.” Thereupon he exclaimed: “It is clear that I slept for seventy years!” He then caught sight of his donkey who had given birth to several generations of mules, and he returned home. He there enquired: “Is the son of Honi the Circle-Drawer still alive?” The people answered him: “His son is no more, but his grandson is still living.” Thereupon he said to them: “I am Honi the Circle-Drawer”, but no one would believe him.

He then went to the Beit Midrash and overheard the scholars say: “The law is as clear to us as in the days of Honi the Circle-Drawer”, for whenever he used to come to the Beit Midrash he would settle for the scholars any difficulty that they had. Whereupon he called out: “I am he!” but the scholars would not believe him nor did they give him the honour due to him. This hurt him greatly and he prayed [for death] and he died…

“Honi HaMeagel”, by Huvy. Honi is famous for drawing a circle in the ground around him and not moving away until God would make it rain. Josephus wrote that Honi was killed during the Hasmonean civil war, around 63 BCE. The Maharsha (Rabbi Shmuel Eidels, 1555-1631) said that people thought he was killed in the war, but actually fell into a deep sleep as the Talmud records.

Honi HaMa’agel, “the Circle-Drawer”, who was renowned for his ability to have his prayers answered, entered a state of deep sleep for seventy years and thereby journeyed to the future! This type of time travel is, of course, not true time travel, and he was unable to go back to his own generation. He prayed for death and was promptly answered.

Travelling back in time, meanwhile, presents far more interesting challenges.

Back to the Future

In 2000, scientists at Princeton University found evidence that it may be possible to exceed the speed of light. As The Guardian reported at the time, “if a particle could exceed the speed of light, the time warp would become negative, and the particle could then travel backwards in time.” This is one of several ways proposed to scientifically explain the possibility of journeying back in time.

The problem with this type of travel is as follows: what happens when a person from the future changes events in the past? The result may be what is often referred to as a “time paradox” or “time loop”. The classic example is a person who goes back to a time before they were born and kills their parent. If they do so, they would never be born, so how could they go back in time to do it?

Remarkably, just as I took a break from writing this, I saw that my son had brought a book from the library upstairs. Out of over 500 books to choose from, he happened to bring Harry Potter and the Prisoner of Azkaban. Now, he is far too young to have read it, or to even known who Harry Potter is. And yet, this is the one book in the Harry Potter series—and possibly the one book in our library—that presents a classic time paradox!

In Prisoner of Azkaban, we read how Harry is about to be killed by a Dementor when he is suddenly saved by a mysterious figure who is, unbeknownst to him, his own future self. After recovering from the attack, he later gets his hands on a “time turner” and goes back in time. It is then that he sees his past self about to be killed by a Dementor, and saves his past self. The big problem, of course, is that Harry could have never gone back in time to save himself had he not already gone back in time to save himself in the first place!

Perhaps a more famous example is James Cameron’s 1984 The Terminator. In this story, John Connor is a future saviour of humanity who is a thorn in the side of the evil, world-ruling robots. Those evil robots decide to send one of their own back to a time before John Connor was born in order to kill his mother—so that John could never be born. Aware of this, Connor sends one of his own soldiers back in time to protect his mother. The soldier and the mother fall in love, and the soldier impregnates her, giving birth to John Connor! In other words, future John Connor sent his own father back in time to protect his mother and conceive himself! This is a time paradox.

Could we find such a time paradox in the Torah? At first glance, there doesn’t appear to be anything like this. However, a deeper look reveals that there may be such a case after all.

When God Wanted to “Kill” Moses

In one of the most perplexing passages in the Torah, we read that when Moses took his family to head back to Egypt and save his people, “God encountered him and sought to kill him.” (Exodus 4:24) To save Moses, his wife Tziporah quickly circumcises their son, sparing her husband’s life. The standard explanation for this is that Moses’ son Eliezer was born the same day that he met God for the first time at the Burning Bush. Moses spent seven days communicating with God, then descended on the eighth day and gathered his things to go fulfil his mission.

However, the eighth day is when he needed to circumcise his son, as God had already commanded his forefather Abraham generations earlier. Moses intended to have the brit milah when they would stop at a hotel along the way, but got caught up with other things. An angel appeared, threatening Moses for failing to do this important mitzvah, so Tziporah took the initiative and circumcised her son. Alternatively, some say it was the baby whose life was at risk.

Whatever the case, essentially all the commentaries agree that God had sent an angel to remind Moses of the circumcision. Who was that angel? It may have been a persecuting angel, and some say he took the form of a frightening snake. Others, like the Malbim (Rabbi Meir Leibush Weisser, 1809-1879) say it was an “angel of mercy” as Moses was entirely righteous and meritorious. Under the circumstances, one’s natural inclination might point to it being the angel in charge of circumcision, as suggested by Sforno (Rabbi Ovadiah ben Yakov, 1475-1550). Who is the angel in charge of circumcision? Eliyahu! In fact, Sforno proposes that the custom of having a special kise kavod, chair of honour, or “chair of Eliyahu” (though Sforno doesn’t say “Eliyahu” by name), might originate in this very Torah passage. Every brit milah today has such an Eliyahu chair, for it is an established Jewish tradition that the prophet-turned-angel Eliyahu visits every brit.

‘Elijah Taken Up to Heaven’

Yet, Eliyahu could not have been there at the brit of Moses’ son, for Eliyahu would not be born for many years! Eliyahu lived sometime in the 9th century BCE. He was a prophet during the reign of the evil king Ahab and his even-more-evil wife Izevel (Jezebel). The Tanakh tells us that Eliyahu never died, but was taken up to Heaven in a fiery chariot (II Kings 2). As is well-known, he transformed into an angel.

The Zohar (I, 93a) explains that when Eliyahu spoke negatively of his own people and told God that the Jews azvu britekha, “have forsaken Your covenant” (I Kings 19:10), God replied:

I vow that whenever My children make this sign in their flesh, you will be present, and the mouth which testified that the Jewish people have abandoned My covenant will testify that they are keeping it.

He henceforth became known as malakh habrit, “angel of the covenant” (Pirkei D’Rabbi Eliezer, 29), a term first used by the later prophet Malachi (3:1).

If Eliyahu is Malakh haBrit, and is present at every circumcision, does this only apply to future circumcisions after his earthly life, or all circumcisions, even those before his time? As an angel that is no longer bound by physical limitations, could he not travel back in time and be present at brits of the past, too? God certainly does transcend time and space, and exists in past, present, and future all at once. This is in God’s very name, a fusion of haya, hoveh, and ihyeh, “was, is, will be”, all in one (see Zohar III, 257b, as well as the Arizal’s Etz Chaim, at the beginning of Sha’ar Rishon, anaf 1). And we already saw how God could send Moses to the distant future and bring him right back to the past. Could He have sent Eliyahu back to the brit of Moses’ son? Such a scenario would result in a classic time loop. How could Eliyahu, a future Torah prophet, save Moses, the very first Torah prophet? Eliyahu could not exist without Moses!

It is important to note here that there were those Sages who believed that Eliyahu was always an angel, from Creation, and came down into bodily form for a short period of time during the reign of Ahab. This is why the Tanakh does not describe Eliyahu’s origins. It does not state who his parents were, or even which tribe he hailed from. Others famously state that “Pinchas is Eliyahu”, ie. that Eliyahu was actually Pinchas, the grandson of Aaron. Pinchas was blessed with eternal life, and after leaving the priesthood, reappeared many years later as Eliyahu to save the Jewish people at a difficult time. He was taken up to Heaven alive as God promised. In the Torah, we read how God blessed Pinchas with briti shalom (Numbers 25:12). Again, that key word “brit” appears—a clue that Pinchas would become Eliyahu, malakh habrit.

While it is hard to fathom, or accept, the possibility of an Eliyahu time paradox, there is one last time paradox that deserves mention. And on this time paradox, all of our Sages do agree…

Wasting Seed: Minor Taboo or Grave Sin?

In this week’s parasha, Vayeshev, we read about the incident of Yehuda and Tamar. Yehuda’s eldest son, Er, marries a beautiful woman named Tamar. Unfortunately, Er “was evil in the eyes of God, and God put him to death.” (Genesis 38:7) As was customary in those days, since Er died without a son, it was expected that his brother, Onan, would perform levirate marriage and take Tamar as his wife. As the Torah describes, the purpose of this is to essentially provide a sort of heir for his childless brother. Onan was happy to marry Tamar, but

knew that the progeny would not be his, and it came about, when he came to his brother’s wife, he wasted [his semen] on the ground, in order not to give seed to his brother. And what he did was evil in the eyes of God, and He put him to death also. (Genesis 38:9-10)

As we know, Yehuda would end up being with Tamar himself, and out of that union would come Peretz, the ancestor of King David.

‘Judah and Tamar’

The big question is: what was it that Er and Onan did that was so despicable to God? The classic answer is that they wasted their seed (as the Torah states above), which is why they were punished so severely. This narrative is then used as proof from the Torah that wasting seed is among the gravest of prohibitions.

And yet, the Torah itself does not actually prohibit wasting seed anywhere, at least not explicitly. Considering how strictly the Sages spoke about not wasting seed, we might be surprised to find that it is not one of the 613 commandments. So, what is the true extent of this prohibition? Where did it come from? And what was really going on with Er and Onan?

A Closer Look at Er and Onan

While the Torah tells us that Er was evil in God’s eyes, it does not explain why. Many commentators (including Rashi and Rabbeinu Bechaye) assume that he must have been evil for the same reason his brother Onan was: for wasting seed. Rabbeinu Bechaye (1255-1340) clarifies that the sin was not the act of wasting seed itself, but rather for an ulterior motive. Er did not want to impregnate Tamar so that her beauty would not be ruined. He wanted her solely for physical pleasure. This is what was despicable to God.

Similarly, a careful look at the Torah makes it clear that Onan’s sin was not wasting seed either. What the Torah says is that Onan did not want to fulfil the mitzvah of levirate marriage. He avoided impregnating Tamar because he “knew the progeny would not be his”, and the reason he spilled his seed on the ground was “in order not to give seed to his brother”. The sin here was not the act of wasting seed, but rather disrespecting his own brother, and refusing to fulfil the mitzvah of levirate marriage.

Such is the opinion of Tzror haMor (Rabbi Abraham Saba, 1440-1508), and we see similar comments by Sforno (Rabbi Ovadiah ben Yakov, 1475-1550). Chizkuni (Rabbi Hezekiah ben Manoach, c. 1250-1310) goes even further, saying that Onan was really out to increase his share of land, for if he would have fulfilled the mitzvah, the child would receive Er’s portion of land, and if not, then Onan would be the inheritor. From these commentaries, and the Torah’s own simple reading, we can definitively conclude that the sin was not the wasting of seed itself but the evil ulterior motives behind it, especially greed and disrespect for a brother.

All of this is right in line with the Torah’s persistent theme of brothers failing to love each other, starting with Cain and Abel and continuing through Isaac and Ishmael, Jacob and Esau, Joseph and his brothers, and Yehuda’s sons. The Torah takes every possible opportunity to remind us to love each other wholeheartedly (as we are all brothers), and that tragedies always befall the Jewish people when we lack brotherly love—as our Sages explicitly state countless times.

Going back to the subject at hand, nowhere else in the Torah is wasting seed an issue. The Torah does state that a man who has an “emission” is impure for purposes of going to the Temple. What he must do is immerse in water, and wait until the evening for the impurity to go away (Leviticus 15:16). No other punishment is prescribed, irrespective of why the man might have the emission.

Spilling Seed, or Spilling Blood?

It is in the Talmud where wasting seed takes on its grave overtones. The Sages compare one who wastes seed to a murderer, an idolater, and an adulterer (Niddah 13a-b). This is quite shocking, considering that murder, idolatry, and adultery are the three “cardinal sins” of Judaism. These are the things one must give up their life for in order to avoid, even if coerced. The Sages are equating wasting seed with the worst possible sins.

In the same pages, we read how Rav Yochanan holds that one who wastes seed “deserves death”. Interestingly, he bases himself on the verses in the Torah concerning the deaths of Er and Onan! Yet, as we’ve seen, their sin was not the act of wasting seed, but their evil ulterior motives. In reality, the Sages are hard-pressed to find a good source for the prohibition. They resort to various colourful interpretations of Scriptural verses in an attempt to illustrate the evils of wasting seed. For example, Isaiah 1:15 says “And when you spread forth your hands, I will hide My eyes from you; when you make many prayers, I will not hear, [because] your hands are full of blood.” Rabbi Elazar says that “hands are full of blood” is referring to those who masturbate, since spilling seed is like spilling blood! This is far from the plain meaning of the verse, which is obviously talking about actual bloodshed.

We should keep in mind that in these Talmudic pages, the Sages are not just prohibiting masturbation or wasting seed, but even for a man to simply touch their “member”—even to urinate! “Rabbi Eliezer said: Whoever holds his member when he urinates is as though he had brought a flood on the world.” Rabbi Tarfon later adds that his hand should be cut off! It goes without saying that the Sages were exceedingly careful to avoid any sexual transgressions, and raised many “fences” to ensure that no one should even come close to sinning so gravely. We must remember that the Talmud often uses hyperbole to get a point across and it isn’t always wise to take statements literally. The Sages themselves question Rabbi Eliezer, and say that not holding one’s member would be very impractical, for “would not the spray splatter on his feet…?”

The point, rather, is to teach us that “such is the art of the evil inclination: Today it incites man to do one wrong thing, and tomorrow it incites him to worship idols and he proceeds to worship them.” (Niddah 13b) The Sages are specifically referring to one who fantasizes to “give himself an erection”, and that such a person “should be expelled”. After all, the yetzer hara works in such a way that it gets a person to make a tiny sin, and slowly leads them to greater transgressions. It might start with a small thought, grow into a consuming fantasy, and eventually leads one to grossly misbehave. In short, the fear is that a person will get accustomed to bad habits, and it will end up leading to more severe transgressions.

Halacha & Kabbalah of Spilling Seed

The Rambam (Rabbi Moshe ben Maimon, 1135-1204) codifies as law the prohibition of wasting seed, whether with one’s partner or on their own (Mishneh Torah, Issurei Biah 21:18):

It is forbidden to release semen wastefully. Therefore a person should not enter his wife and release outside of her… Those who release semen with their hands, beyond the fact that they commit a great transgression, a person who does this will abide under a ban of ostracism. Concerning them, it is said: “Your hands are filled with blood.” It is as if they killed a person.

The Rambam makes a distinction between a situation of husband and wife versus a man doing it on his own, which is far worse and likened to “murder”. Having said that, many other great authorities in Jewish law were more lenient when it comes to wasting seed, especially when the intention is not evil. The Rambam’s contemporary, Rabbi Yehuda haHasid (1150-1217), wrote in his Sefer Hasidim that while masturbation is forbidden, and requires a great deal of penance to repair, it is occasionally permitted if it will prevent a person from a more serious sin. On that note, the Rambam himself wrote elsewhere (Commentary on the Mishnah, Sanhedrin 7:4) that wasting seed is not an explicit Torah prohibition, and carries no actual punishment of any kind. However, he writes in the same place that although many things are permitted when done consensually between husband and wife, it is nonetheless important to be exceedingly modest when it comes to sexuality.

The later Kabbalists understood that the Torah carries no explicit punishment for wasting seed, but found an allusion to a more mystical punishment. They taught that wasting seed produces banim shovavim, literally “wayward children” (a term that comes from Jeremiah 3:14 and 3:22). These impure spirits—potential souls that are brought into this world without a body—attach to a man’s neck and cause him great damage, and can harm his children, too. There is no doubt that the Rambam, being a strict rationalist and staying away from anything “Kabbalistic”, would disagree with this approach. The Rambam did not believe in demons or evil spirits, and refused to accept the validity of many Kabbalistic ideas and practices.

The Arizal (Rabbi Isaac Luria, 1534-1572), perhaps the greatest of Kabbalists, was a major proponent of the banim shovavim notion. Since his time, it has become customary in some communities to focus on purifying from sexual sins and from wasted seed during the weeks when we read the consecutive parashas of Shemot, Va’era, Bo, Beshalach, Yitro, and Mishpatim. Since the initials of these parashas spell “shovavim”, it is thought to be an auspicious time for such repentance. Yet even the Arizal taught that wasting seed is primarily a problem when a person does so on their own, for selfish, lustful reasons. If one is married, and there is genuine loving intimacy between husband and wife, the prohibition is no longer so clear cut. (See, for example, Sha’ar HaMitzvot on Noach).

Indeed, many authorities permitted wasting seed in the context of a husband and wife being together—as long as they are not like Er or Onan, and have pure intentions coming out of true love and passion. Among those that held this opinion include the tosafist Rabbi Isaac ben Shmuel (c. 1115-1184, in his comments to Yevamot 34b) and the Maharsha (Rabbi Shmuel Eidels, 1555-1631, in his comments on Nedarim 20a). The tosafist Rabbi Isaiah di Trani (c. 1180-1250) stated it most emphatically: “one whose intention is to satisfy his desires [for his wife] does not transgress, for anything that a man wants to do with his wife he can do, and it is not considered wasting seed”! (מי שכונתו להשלים תאות יצרו אינו עובר, שכל מה שאדם רוצה לעשות באשתו עושה ולא יקרא משחית זרעו, see Tosfot Rid on Yevamot 12b.)

In fact, even the Arizal taught that, in certain special cases, wasted seed can serve a positive purpose. In Sha’ar HaGilgulim (ch. 26), we read how the ten drops of wasted seed that unintentionally emerged out of Joseph (as per the famous Midrash) resulted in levushim, protective “garments” for the soul. The seed wasted indirectly by tzaddikim may similarly produce such protective garments, especially when it happens during proper, loving, holy zivug (union) between husband and wife. Such union, while not fruitful in this world, corresponds to “heavenly unions” that are spiritually fruitful. It is important to repeat that this entails being an actual tzaddik—being righteous, just, observant, modest, humble, selfless—and being intimate in a holy, loving, kosher, monogamous union.

On that note, it is worth mentioning that a couple that is childless, or already pregnant, is absolutely allowed to continue to be intimate, and this is not at all considered “wasting seed”. (The Talmud adds that intimacy during the third trimester is particularly healthy for both mother and baby, see Niddah 31a.) At the very start of Sha’ar HaMitzvot, the Arizal explains that such unions might not produce physical children, but they produce many spiritual children. This is one meaning for the verse in the Torah that says Abraham and Sarah “made souls” in Charan (Genesis 12:5)—although they were physically childless, they had produced many souls in Heaven, and these souls later came down into human form. In fact, there are those who say these souls are given to converts, who receive a Jewish soul upon their successful conversion. The souls that Abraham and Sarah made all those years come down into the bodies of converts, which is the deeper reason why all converts are referred to as “ben Avraham” and “bat Sarah”.

To summarize and conclude, the issue of spilled seed could indeed be a serious one. There is room to be lenient in certain situations, such as the case of a young, unmarried gentleman, whose frustration might reach a point where he might be led to worse sins. The Sages recognized how incredibly difficult the latter case can be, and stated that a young bachelor who lives in the city and can still hold himself back from sexual sins is so praiseworthy that God personally calls out his name in Heaven every day (Pesachim 113a). In the case of a married couple with loving intentions, many authorities state there is no issue of “wasting seed” at all, and any form of intimacy is permitted. That helps to explain why Rabbi Chiya said it is best to stay married no matter what, and to always treat one’s wife exceedingly well—even if she is the worst kind of wife—because wives “save us from sin” (Yevamot 63a). It is fitting to end with another famous adage from the Talmud (Sukkah 52b): אבר קטן יש לו לאדם מרעיבו שבע משביעו רעב “There is a small organ in a man’s body—if he starves it, he is satisfied; if he satisfies it, he starves.”
