So Joab went and told the king, and David summoned Absalom, who came to him and bowed facedown before him. Then the king kissed Absalom.
Joab tells David, David summons Absalom, Absalom bows before him, and the king kisses him.
It closes the chapter with David's outward act of reconciliation.
28Now Absalom lived in Jerusalem two years without seeing the face of the king. 29Then he sent for Joab to send him to the king, but Joab refused to come to him. 30Then Absalom said to his servants, “Look, Joab’s field is next to mine, and he has barley there. Go and set it on fire!” 31Then Joab came to Absalom’s house and demanded, “Why did your servants set my field on fire?” 32“Look,” said Absalom, “I sent for you and said, ‘Come here. I want to send you to the king to ask: Why have I come back from Geshur? It would be better for me if I were still there.’ So now, let me see the king’s face, and if there is iniquity in me, let him kill me.” 33So Joab went and told the king, and David summoned Absalom, who came to him and bowed facedown before him. Then the king kissed Absalom.
