2 Samuel 12:21-23

21His servants asked him, “What is this thing you have done? You fasted and wept while the child was still alive, but as soon as the child died, you got up and ate food.”

22He replied, “While the child was yet alive, I fasted and wept, for I thought, ‘Who knows? Adonai might be gracious to me and let the child live.’

23But now that he has died, why should I fast? Can I bring him back again? It is I who will be going to him, but he will never return to me.”
