Genesis 48:16

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

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

15 Then he blessed Joseph and said: “May the God before whom my fathers Abraham and Isaac walked, the God who has been my shepherd all my life to this day,

16 the angel who has redeemed me from all harm— may He bless these boys. And may they be called by my name and the names of my fathers Abraham and Isaac, and may they grow into a multitude upon the earth.”

17 When Joseph saw that his father had placed his right hand on Ephraim’s head, he was displeased and took his father’s hand to move it from Ephraim’s head to Manasseh’s.

18 “Not so, my father!” Joseph said. “This one is the firstborn; put your right hand on his head.”

19 But his father refused. “I know, my son, I know!” he said. “He too shall become a people, and he too shall be great; nevertheless, his younger brother shall be greater than he, and his offspring shall become a multitude of nations.”
