2 Samuel 12:14-16

12:14 Nonetheless, because you have treated the Lord with such contempt in this matter, the son who has been born to you will certainly die.”

12:15 Then Nathan went to his home. The Lord struck the child that Uriah’s wife had borne to David, and the child became very ill. 12:16 Then David prayed to God for the child and fasted. He would even go and spend the night lying on the ground.
