Why Korach's Lineage Stops at Levi and Not Jacob

(Numbers 16:1:) NOW KORACH BEN IZHAR BEN KOHATH BEN LEVI TOOK. But it is not written "ben Jacob" or "ben Israel." This is what Scripture says (Genesis 49:6): "LET NOT MY SOUL ENTER INTO THEIR COUNCIL" — these are the spies. "AND LET NOT MY GLORY BE UNITED WITH THEIR ASSEMBLY" (ibid.) — this is Korach. Jacob said before the Holy One, blessed be He: Master of the Universe, let not my name be remembered in connection with the spies, nor in connection with the dissension of Korach — with those wicked ones who are destined to provoke anger. And when shall my name be joined together? When they unite themselves to stand upon the platform (as singers): (I Chronicles 6:22–23:) BEN ASIR BEN EBIASAPH BEN KORACH BEN IZHAR BEN KOHATH BEN LEVI BEN ISRAEL.
