2 Samuel 3:12-13, 21

And Abner sent messengers to David on his behalf, saying, “To whom does the land belong? Make your covenant with me, and behold, my hand shall be with you to bring over all Israel to you.” And he said, “Good; I will make a covenant with you. But one thing I require of you; that is, you shall not see my face unless you first bring Michal, Saul’s daughter, when you come to see my face.”

And Abner said to David, “I will arise and go and will gather all Israel to my lord the king, that they may make a covenant with you, and that you may reign over all that your heart desires.” So David sent Abner away, and he went in peace.
