'At His Right Hand' in the Bible

So Bath-sheba went to King Solomon to have talk with him on Adonijah's account. And the king got up to come to her, and went down low to the earth before her; then he took his place on the king's seat and had a seat made ready for the king's mother and she took her place at his right hand.

And he said, Give ear now to the word of the Lord: I saw the Lord seated on his seat of power, with all the army of heaven in their places round him at his right hand and at his left.
