2 Samuel 3:11

9God do so to Abner, and more also, if, as the LORD has sworn to David, I don’t do even so to him:

10to transfer the kingdom from Saul’s house, and to set up David’s throne over Israel and over Judah, from Dan even to Beersheba.”

11He could not answer Abner another word, because he was afraid of him.

12Abner sent messengers to David on his behalf, saying, “Whose is the land?” and saying, “Make your alliance with me, and behold, my hand will be with you to bring all Israel around to you.”

13David said, “Good. I will make a treaty with you, but one thing I require of you. That is, you will not see my face unless you first bring Michal, Saul’s daughter, when you come to see my face.”
