2 Samuel 12:21-23

Then his servants said to him, “What is this thing that you have done? You fasted and wept for the child while he was alive; but when the child died, you arose and ate food.” He said, “While the child was still alive, I fasted and wept, for I said, ‘Who knows whether the LORD will be gracious to me, that the child may live?’ But now he is dead. Why should I fast? Can I bring him back again? I shall go to him, but he will not return to me.”
