Genesis 48:13-18

13And 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.

14But 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.

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

16the Angel who has delivered me from all harm —may he bless these boys. May they be called by my name and the names of my fathers Abraham and Isaac, and may they increase greatly on the earth.” 17When Joseph saw his father placing his right hand on Ephraim’s head he was displeased; so he took hold of his father’s hand to move it from Ephraim’s head to Manasseh’s head.

18Joseph said to him, “No, my father, this one is the firstborn; put your right hand on his head.”
