2 Samuel 12:19-23

But when David saw that his servants were whispering together, David perceived that the child was dead; so David said to his servants, “Is the child dead?” And they said, “He is dead.” So David arose from the ground, washed, anointed himself, and changed his clothes; and he came into the house of the LORD and worshiped. Then he came to his own house, and when he requested, they set food before him and he ate. Then his servants said to him, “What is this thing that you have done? While the child was alive, you fasted and wept; 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, the LORD may be gracious to me, that the child may live.’ But now he has died; why should I fast? Can I bring him back again? I will go to him, but he will not return to me.”
