'His Right Hand' in the Bible

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

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

When Joseph saw that his father laid his right hand on Ephraim’s head, it displeased him; and he grasped his father’s hand to remove it from Ephraim’s head to Manasseh’s head.
