23The son of Dan: Hushim. 24The sons of Naphtali: Jahzeel, Guni, Jezer, and Shillem. 25These are the sons of Jacob born to Bilhah, whom Laban gave to his daughter Rachel — seven in all. 26All those belonging to Jacob who came to Egypt— his direct descendants, besides the wives of Jacob’s sons— numbered sixty-six persons. 27And with the two sons who had been born to Joseph in Egypt, the members of Jacob’s family who went to Egypt were seventy in all.
