Genesis 41:51

Now to Joseph in the land of Egypt were born Manasseh and Ephraim, whom Asenath, the daughter of Potiphera, priest of On, bore to him.

Now it happened after these things that Joseph was told, “Behold, your father is sick.” So he took his two sons Manasseh and Ephraim with him.

“So now your two sons, who were born to you in the land of Egypt before I came to you in Egypt, are mine; Ephraim and Manasseh shall be mine, as Reuben and Simeon are.

But Israel stretched out his right hand and laid it on the head of Ephraim, who was the younger, and his left hand on Manasseh’s head, crossing his hands, although Manasseh was the firstborn.

For the sons of Joseph were two tribes, Manasseh and Ephraim, and they did not give a portion to the Levites in the land, except cities to live in, with their pasture lands for their livestock and for their property.

And this was the lot for the tribe of Manasseh, for he was the firstborn of Joseph. To Machir the firstborn of Manasseh, the father of Gilead, were allotted Gilead and Bashan, because he was a man of war.

Now it happened in due time that Hannah conceived and gave birth to a son; and she named him Samuel, saying, “Because I have asked him of Yahweh.”
