Exodus 6:13-15

But GOD again laid out the facts to Moses and Aaron regarding the Israelites and Pharaoh king of Egypt, and he again commanded them to lead the Israelites out of the land of Egypt. These are the heads of the tribes: The sons of Reuben, Israel’s firstborn: Hanoch, Pallu, Hezron, and Carmi—these are the families of Reuben. The sons of Simeon: Jemuel, Jamin, Ohad, Jakin, Zohar, and Saul, the son of a Canaanite woman—these are the families of Simeon.
