Genesis 46:20

20 And to Joseph in the land of Egypt were born Manasseh and Ephraim, whom Asenath, the daughter of Poti-phera priest of On, bore to him. And the sons of Manasseh: his wife bore Asriel, and his Aramean concubine bore Machir. And Machir begot Gilead. And the sons of Manasseh's brother, Ephraim: Shuthelah and Tahan. And the sons of Shuthelah: Eran.
