'Right Hand' in the Bible

Is not the whole land before you? separate yourself, I pray you, from me: if you will take the left hand, then I will go to the right; or if you depart to the right hand, then I will go to the left.

And now if you will deal kindly and truly with my master, tell me: and if not, tell me; 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 hand, and Manasseh in his left hand toward Israel's right hand, and brought them near unto him.

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

And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father's hand, to remove it from Ephraim's head unto Manasseh's head.

And Joseph said unto his father, Not so, my father: for this is the firstborn; put your right hand upon his head.
