18 On the seventh day the child died. David's servants were afraid to tell him. They said, "What do we do now? While the child was living he wouldn't listen to a word we said. Now, with the child dead, if we speak to him there's no telling what he'll do." 19 David noticed that the servants were whispering behind his back, and realized that the boy must have died. He asked the servants, "Is the boy dead?" "Yes," they answered. "He's dead." 20 David got up from the floor, washed his face and combed his hair, put on a fresh change of clothes, then went into the sanctuary and worshiped. Then he came home and asked for something to eat. They set it before him and he ate. 21 His servants asked him, "What's going on with you? While the child was alive you fasted and wept and stayed up all night. Now that he's dead, you get up and eat." 22 "While the child was alive," he said, "I fasted and wept, thinking God might have mercy on me and the child would live. 23 But now that he's dead, why fast? Can I bring him back now? I can go to him, but he can't come to me." 24 David went and comforted his wife Bathsheba. And when he slept with her, they conceived a son. When he was born they named him Solomon. God had a special love for him 25 and sent word by Nathan the prophet that God wanted him named Jedidiah (God's Beloved).
26 Joab, at war in Rabbah against the Ammonites, captured the royal city. 27 He sent messengers to David saying, "I'm fighting at Rabbah, and I've just captured the city's water supply. 28 Hurry and get the rest of the troops together and set up camp here at the city and complete the capture yourself. Otherwise, I'll capture it and get all the credit instead of you." 29 So David marshaled all the troops, went to Rabbah, and fought and captured it. 30 He took the crown from their king's head - very heavy with gold, and with a precious stone in it. It ended up on David's head. And they plundered the city, carrying off a great quantity of loot. 31 David emptied the city of its people and put them to slave labor using saws, picks, and axes, and making bricks. He did this to all the Ammonite cities. Then David and the whole army returned to Jerusalem.

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."

(Read 2 Samuel 12:26-31)
To be thus severe in putting the children of Ammon to slavery was a sign that David's heart was not yet made soft by repentance, at the time when this took place. We shall be most compassionate, kind, and forgiving to others, when we most feel our need of the Lord's forgiving love, and taste the sweetness of it in our own souls.
