19 But when David saw that his servants were whispering together, David perceived that the child was dead; and David said to his servants, “Is the child dead?”
They said, “He is dead.” 20 Then David arose from the earth, and washed, and anointed himself, and changed his clothing; and he came into the house of Yahweh, and worshiped: then he came to his own house; and when he required, they set bread before him, and he ate. 21 Then said his servants to him, “What is this that you have done? You fasted and wept for the child while he was alive; but when the child was dead, you rose up and ate bread.” 22 He said, “While the child was yet alive, I fasted and wept; for I said, ‘Who knows whether Yahweh will not be gracious to me, that the child may live?’ 23 But now he is dead, why should I fast? Can I bring him back again? I shall go to him, but he will not return to me.” 24 David comforted Bathsheba his wife, and went in to her, and lay with her.

David now penned the 51st Psalm, in which, though he had been assured that his sin was pardoned, he prays earnestly for pardon, and greatly laments his sin. He was willing to bear the shame of it, to have it ever before him, to be continually upbraided with it. God gives us leave to be earnest with him in prayer for particular blessings, from trust in his power and general mercy, though we have no particular promise to build upon. David patiently submitted to the will of God in the death of one child, and God made up the loss to his advantage, in the birth of another. The way to have creature comforts continued or restored, or the loss made up some other way, is cheerfully to resign them to God. God, by his grace, particularly owned and favoured that son, and ordered him to be called Jedidiah, Beloved of the Lord. Our prayers for our children are graciously and as fully answered when some of them die in their infancy, for they are well taken care of, and when others live, "beloved of the Lord."
