2 Samuel 12:20

Then David arose from the earth. If David's grief had been occasioned by love for the child, then its death and the consciousness that, while his guilt had caused its sickness, his prayers had not availed to save it, would have aggravated his anguish. There was much personal regard for the child, which had been made the more precious by these very eyelets. But David's sorrow was, as we have seen, that of penitence, and not that of natural affection. When, therefore, the threatened penalty had been paid by the death of the child, David felt it to be his duty to show his resignation, and therefore he went into the sanctuary and worshipped, in proof that he acknowledged the justice of God's dealings, and was content to bear the punishment as his righteous desert.
