Secrets of the Jewish Calendar

Today we welcome the new month of Kislev. It is well-known that the months of the Hebrew year parallel the Tribes of Israel and the zodiacal constellations. According to Sefer Yetzirah, each month also embodies one of twelve fundamental aspects of humanity and life: sight, sound, smell, speech, taste, touch, action, motion, temper, joy, thought, and sleep (ראיה, שמיעה, ריחה, שיחה, לעיטה, תשמיש, מעשה, הלוך, רוגז, שחוק, הרהור, שינה). Each of these further corresponds to twelve main parts and organs of the human body, and actually emerges at their core from the twelve “elemental” letters of the Hebrew alphabet, as well as the twelve permutations of God’s Ineffable Name. Recall that Sefer Yetzirah divides up the alphabet into three categories: “mother” letters, “doubled” letters, and “elemental” or “simple” letters (for more on these, see here). Continue reading

Origins & Secrets of Birkat Levanah

This weekend we welcome the month of Cheshvan and celebrate the first Rosh Chodesh of the new year 5785. In ancient times, the Sanhedrin would officially announce the start of a new month upon sighting of the new moon. Once the Sanhedrin was disbanded, the Sages fixed a set calendar for the millennia ahead. And since then, instead of a formal announcement of a new month upon new moon sighting, we recite a birkat levanah, a “blessing on the moon”. Where exactly did this blessing and practice originate? And what is the meaning behind its enigmatic text?

The earliest source for birkat levanah is thought to be a passage in the tractate Sanhedrin. Amidst a discussion of examining witnesses in a Jewish court, the Talmud asks a side-question: “Until when may one recite the blessing on the new month?” (41b) Two answers are given, one that it should be recited within the first week of the month (seven days) and another that it can be recited until just after the full moon, ie. the sixteenth day of the month, since at that point the moon begins to wane.

Seventeen Tamuz and the Ten Plagues

Next Tuesday is the seventeenth of Tamuz, commemorating a handful of tragedies in Jewish history starting with the shattering of the Tablets following the sin of the Golden Calf. A careful examination of Torah chronology reveals that there may be one more major event that took place at this time, and it involves the Ten Plagues in Egypt. While the Torah describes in great detail how the Ten Plagues came about, it says very little about their timing. All we know is that the final plague upon the firstborn was on the fifteenth of Nisan. Can we work backwards from this point and create an exact timeline of when the Ten Plagues occurred?
