Exodus 6:13-15

And Jehovah spake unto Moses and unto Aaron, and gave them a charge unto the children of Israel, and unto Pharaoh king of Egypt, to bring the children of Israel out of the land of Egypt. These are the heads of their fathers’ houses. The sons of Reuben the first-born of Israel: Hanoch, and Pallu, Hezron, and Carmi; these are the families of Reuben. And the sons of Simeon: Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Shaul the son of a Canaanitish woman; these are the families of Simeon.
