II Samuel 12:16, 19-20

David therefore pleaded with God for the child, and David fasted and went in and lay all night on the ground.

When David saw that his servants were whispering, David perceived that the child was dead. Therefore David said to his servants, “Is the child dead?” And they said, “He is dead.” So David arose from the ground, washed and anointed himself, and changed his clothes; and he went into the house of the LORD and worshiped. Then he went to his own house; and when he requested, they set food before him, and he ate.
