2 Samuel 6:21-23

21And David said to Michal, "It was before the Lord, who chose me above your father and above all his house, to appoint me as prince over Israel, the people of the Lord—and I will celebrate before the Lord.

22I will make myself yet more contemptible than this, and I will be abased in your eyes. But by the female servants of whom you have spoken, by them I shall be held in honor."

23And Michal the daughter of Saul had no child to the day of her death.
