2 Samuel 12:19-23

But when David saw that his servants were whispering together, David perceived that the child was dead; and David said unto his servants, Is the child dead? And they said, He is dead. Then David arose from the earth, and washed, and anointed himself, and changed his apparel; and he came into the house of Jehovah, and worshipped: then he came to his own house; and when he required, they set bread before him, and he did eat. Then said his servants unto him, What thing is this that thou hast done? thou didst fast and weep for the child, while it was alive; but when the child was dead, thou didst rise and eat bread. And he said, While the child was yet alive, I fasted and wept: for I said, Who knoweth whether Jehovah will not be gracious to me, that the child may live? But now he is dead, wherefore should I fast? can I bring him back again? I shall go to him, but he will not return to me.
