Genesis 48:12-14

12Then Joseph took them from his father’s knees and bowed with his face to the ground.

13Then Joseph took them both — with his right hand Ephraim toward Israel’s left, and with his left hand Manasseh toward Israel’s right — and brought them to Israel.

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