2 Samuel 12:19-20

19But when David saw that his servants were whispering to one another, he realized that the child was dead. So David said to them, “Is the child dead?” And they said, “He is dead.”

20Then David got up from the ground, washed, anointed himself [with olive oil], changed his clothes, and went into the house of the Lord and worshiped. Then he came [back] to his own house, and when he asked, they set food before him and he ate.
