Genesis 48:13; Genesis 48:14; Genesis 48:19

13 And Joseph took them both, Ephraim in his right hand toward Israel's left hand, and Manasseh in his left hand toward Israel's right hand, and brought them near him.

14 And Israel stretched out his right hand and laid it on the head of Ephraim, who was the younger, and his left hand on the head of Manasseh, crossing his hands (for Manasseh was the firstborn).

19 But his father refused and said, "I know, my son, I know. He also shall become a people, and he also shall be great. Nevertheless, his younger brother shall be greater than he, and his offspring shall become a multitude of nations."
