2 Samuel 12:19-23

19But David saw that his servants whispered, and David perceived that the child was dead; and David said to his servants, Is the child dead? And they said, He is dead.

20Then David arose from the earth, and washed, and anointed himself, and changed his clothing, and entered into the house of Jehovah and worshipped; then he came to his own house and required them to set bread before him, and he ate.

21And his servants said to him, What thing is this which thou hast done? thou didst fast and weep for the child alive; but as soon as the child is dead, thou dost rise and eat bread.

22And he said, While the child was yet alive, I fasted and wept; for I thought, Who knows? [perhaps] Jehovah will be gracious to me, that the child may live.

23But 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.
