'Right Hand' in the Bible

Isn't the whole land before you? Please separate yourself from me. If you go to the left hand, then I will go to the right. Or if you go to the right hand, then I will go to the left."

Now if you will deal kindly and truly with my master, tell me. If not, tell me, that I may turn to the right hand, or to the left."

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

Israel stretched out his right hand, and laid it on Ephraim's head, who was the younger, and his left hand on Manasseh's head, guiding his hands knowingly, for Manasseh was the firstborn.

When Joseph saw that his father laid his right hand on the head of Ephraim, it displeased him. He held up his father's hand, to remove it from Ephraim's head to Manasseh's head.

Joseph said to his father, "Not so, my father; for this is the firstborn; put your right hand on his head."
