Why Jacob's Name Was Left Out of Korah's Genealogy

“Koraḥ, son of Yitzhar son of Kehat son of Levi” – why is it not written: Son of Jacob or son of Israel? That is what the verse said:10When Jacob blessed his children. “Let myself not come in their counsel” (Genesis 49:6) – these are the spies; “let my glory not be associated with their assembly” (Genesis 49:6) – this is Koraḥ. Jacob said before the Holy One blessed be He: ‘Master of the universe, neither regarding the spies, nor in Koraḥ’s dispute, let my name be mentioned with those wicked ones.

When should my name be mentioned? When their lineage is recorded and they are standing upon the platform’11They are performing the Levite service in the Temple. – “son of Taḥat, son of Asir, son of Evyasaf, son of Koraḥ, son of Yitzhar, son of Kehat, son of Levi, son of Israel” (I Chronicles 6:22–23). “And Datan and Aviram” – from here they said: ‘Woe unto the wicked one, woe unto his neighbor,’ as Datan and Aviram were neighbors of Koraḥ, who was situated in the south, as it is written: “The families of the sons of Kehat shall encamp on the side of the Tabernacle to the south” (Numbers 3:29).

The banner of Reuben was adjacent to them, as it is stated: “The banner of the camp of Reuben is to the south” (Numbers 2:10). But the banner of Judah was in the east, and Issachar and Zebulun were with him, as it is stated: “Those encamping at the front, to the east, are the banner of the camp of Judah” (Numbers 2:3). Moses and Aaron were adjacent to them, as it is written: “Those encamped in front of the Tabernacle, to the east, in front of the Tent of Meeting: Moses, Aaron, and his sons” (Numbers 3:38).

Because they were adjacent to the Torah, they merited becoming masters of Torah, as it is written: “Judah, My lawgiver” (Psalms 60:9), and it is written: “From the children of Issachar, possessors of understanding of the times” (I Chronicles 12:33), and it is written: “From Zebulun, those who ply the scribe’s quill” (Judges 5:14). But Datan and Aviram, who were neighbors of a disputant, were stricken with him and were eliminated from the world.
