'Right hand' in the Bible

So Bathsheba went to King Solomon to speak to him for Adonijah. And the king rose to meet her, bowed before her, and sat down on his throne; then he had a throne set for her, the king’s mother, and she sat on his right.

Micaiah said, “Therefore, hear the word of the Lord. I saw the Lord sitting on His throne, and all the host (army) of heaven standing by Him on His right hand and on His left.
