'Right hand' in the Bible

And now if you will deal kindly and truthfully with my master, tell me. And if not, tell me so that I may turn to the right hand or to the left.

And Joseph took them both, Ephraim in his right hand toward Israel's left, and Manasseh in his left toward Israel's right hand. And he brought them near to him.

And Israel stretched out his right hand, and laid it on Ephraim's head, who was the younger, and his left on Manasseh's head, crossing his hands. For Manasseh was the first-born.

And Joseph saw that his father laid his right hand on the head of Ephraim, and it was evil in his eyes. And he held up his father's hand to remove it from Ephraim's head to Manasseh's head.

And Joseph said to his father, Not so, my father. For this is the first-born. Put your right hand on his head.
