'His Right Hand' in the Bible

Joseph positioned them; he put Ephraim on his right hand across from Israel's left hand, and Manasseh on his left hand across from Israel's right hand. Then Joseph brought them closer to his father.

Israel stretched out his right hand and placed it on Ephraim's head, although he was the younger. Crossing his hands, he put his left hand on Manasseh's head, for Manasseh was the firstborn.

When Joseph saw that his father placed his right hand on Ephraim's head, it displeased him. So he took his father's hand to move it from Ephraim's head to Manasseh's head.
