1 Kings 2:19-20

19And Bathsheba 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 he caused a throne to be set for the king's mother, and she sat on his right hand.

20Then she said, I desire one small petition of thee; refuse me not. And the king said to her, Ask, my mother, for I will not refuse thee.
