Genesis 48:12-14

12And Joseph brought them out from between his knees, and he bowed himself with his face to the earth. 13And 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 to him. 14And Israel stretched out his right hand, and laid it upon Ephraim’s head, who was the younger, and his left hand upon Manasseh’s head, guiding his hands knowingly; for Manasseh was the firstborn.
