Genesis 48:12-14

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

13Then Joseph took the two of them—Ephraim with his right hand across from Israel’s left, and Manasseh with his left hand across from Israel’s right—and brought them close to him.

14But Israel stretched out his right hand and placed it upon Ephraim’s head (though he was the younger), and his left hand upon Manasseh’s head, crossing his hands (though Manasseh was the firstborn).
