2 Samuel 12:21-23

21His officers said to him, ‘We do not understand what you are doing. While the child was still alive, you refused to eat food and you wept. But now that the child is dead you are no longer weeping. You are moving around and you are eating. Why?’

22David replied, ‘While the child was still alive, I wept and I did not eat anything. I thought that perhaps the Lord would be kind to me. I thought that he might let the child live.

23But now the child is dead. Even if I fast and I pray, I cannot bring him back to me. One day, I will go to the place where he is. But he will never come back here to me.’
