15 Then Nathan went back to his house. And the hand of the Lord was on David's son, the child of Uriah's wife, and it became very ill. 16 So David made prayer to God for the child; and he took no food day after day, and went in and, stretching himself out on the earth, was there all night. 17 And the chief men of his house got up and went to his side to make him get up from the earth, but he would not; and he would not take food with them. 18 And then on the seventh day the child's death took place. And David's servants were in fear of giving him the news of the child's death: for they said, Truly, while the child was still living he gave no attention when we said anything to him: what will he do to himself if we give him word that the child is dead? 19 But when David saw that his servants were talking together quietly, he was certain that the child was dead: and he said to his servants, Is the child dead? and they said, He is.

Commentary on 2 Samuel 12:15-25
(Read 2 Samuel 12:15-25)
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."
