Exodus 6:13

10 And the Lord said to Moses,

11 Go in and say to Pharaoh, king of Egypt, that he is to let the children of Israel go out of his land.

12 And Moses, answering the Lord, said, See, the children of Israel will not give ear to me; how then will Pharaoh give ear to me, whose lips are unclean?

13 And the word of the Lord came to Moses and Aaron, with orders for the children of Israel and for Pharaoh, king of Egypt, to take the children of Israel out of the land of Egypt.

14 These are the heads of their fathers' families: the sons of Reuben the oldest son of Israel: Hanoch and Pallu, Hezron and Carmi: these are the families of Reuben.

15 And the sons of Simeon: Jemuel and Jamin and Ohad and Jachin and Zohar and Shaul, the son of a woman of Canaan: these are the families of Simeon.

16 And these are the names of the sons of Levi in the order of their generations: Gershon and Kohath and Merari: and the years of Levi's life were a hundred and thirty-seven.
