Exodus 6:13-15

But the LORD spoke to Moses and Aaron and gave them orders for the Israelites and for Pharaoh, the king of Egypt. The LORD commanded Moses and Aaron to lead the people of Israel out of Egypt. These are the ancestors of some of the clans of Israel: The sons of Reuben, Israel’s oldest son, were Hanoch, Pallu, Hezron, and Carmi. Their descendants became the clans of Reuben. The sons of Simeon were Jemuel, Jamin, Ohad, Jakin, Zohar, and Shaul. (Shaul’s mother was a Canaanite woman.) Their descendants became the clans of Simeon.
