Genesis 48:5, 13, 14, 18-20

“Now then, your two sons born to you in Egypt before I came to you here will be reckoned as mine; Ephraim and Manasseh will be mine, just as Reuben and Simeon are mine.

And Joseph took both of them, Ephraim on his right toward Israel’s left hand and Manasseh on his left toward Israel’s right hand, and brought them close to him.

But Israel reached out his right hand and put it on Ephraim’s head, though he was the younger, and crossing his arms, he put his left hand on Manasseh’s head, even though Manasseh was the firstborn.

Joseph said to him, “No, my father, this one is the firstborn; put your right hand on his head.” But his father refused and said, “I know, my son, I know. He too will become a people, and he too will become great. Nevertheless, his younger brother will be greater than he, and his descendants will become a group of nations.” He blessed them that day and said, “In your name will Israel pronounce this blessing: ‘May God make you like Ephraim and Manasseh.’ ” So he put Ephraim ahead of Manasseh.
