Exodus 6:13-15

Now the LORD spoke to Moses and Aaron about the Israelites and Pharaoh king of Egypt, and he commanded them to bring the Israelites out of Egypt. These were the heads of their families: The sons of Reuben the firstborn son of Israel were Hanok and Pallu, Hezron and Karmi. These were the clans of Reuben. The sons of Simeon were Jemuel, Jamin, Ohad, Jakin, Zohar and Shaul the son of a Canaanite woman. These were the clans of Simeon.
