Genesis 46:11

Now these are the names of the sons of Israel who came to Egypt with Jacob; they came each one with his household:

These are the names of the sons of Levi according to their generations: Gershon and Kohath and Merari; and the years of Levi’s life were 137 years.

And these are those who were numbered of the Levites according to their families: of Gershon, the family of the Gershonites; of Kohath, the family of the Kohathites; of Merari, the family of the Merarites.

These are the sons of Israel: Reuben, Simeon, Levi, Judah, Issachar, Zebulun,

The sons of Levi were Gershon, Kohath, and Merari.

The sons of Levi were Gershom, Kohath, and Merari.
