2 Samuel 12:21-23

His servants asked him, “What’s going on with you? While the child was alive you fasted and wept and stayed up all night. Now that he’s dead, you get up and eat.” “While the child was alive,” he said, “I fasted and wept, thinking GOD might have mercy on me and the child would live. But now that he’s dead, why fast? Can I bring him back now? I can go to him, but he can’t come to me.”
