'Right hand' in the Bible

Bath-sheba therefore went to king Solomon, to speak to him for Adonijah. And the king rose up to meet her, and bowed himself to her, and sat down on his throne, and caused a seat to be set for the king's mother; and she sat on his right hand.

Micaiah said, "Therefore hear the word of Yahweh. I saw Yahweh sitting on his throne, and all the army of heaven standing by him on his right hand and on his left.
