'Right hand' in the Bible

And now, if ye will deal kindly and truly with my master, tell me; and if not, tell me; and I will turn to the right hand or to the left.

And 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.

But Israel stretched out his right hand, and laid it on Ephraim's head now he was the younger and his left hand on Manasseh's head; guiding his hands intelligently, for Manasseh was the firstborn.

When Joseph saw that his father laid his right hand on the head of Ephraim, it was evil in his eyes; and he took hold of 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 firstborn: put thy right hand on his head.
