Genesis 48:13-19

13And 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. 14But 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. 15Then he blessed Joseph and said:

17When 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.”

19But 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.”
