In parashat Korach, we read how “the earth opened her mouth and swallowed them up, and their households, and all the men that were with Korach” (Numbers 16:32). Evidently, Korach and his entire family perished. Yet, later on the Torah tells us: “And the earth opened its mouth and swallowed them up with Korach… but the sons of Korach did not die.” (Numbers 26:10-11) Apparently, his sons actually survived! We know this must be the case because there are a number of Psalms (such as numbers 42 to 49) which begin with a byline saying they were written by the “sons of Korach”. How is this possible?
