Absalom lived in Jerusalem two years without ever seeing the king's face.
Absalom called for Joab in order to send Joab to the king, but Joab refused to come. Absalom called for Joab a second time, but he still wouldn't come.
So Absalom said to his servants, "Look, Joab's property is next to mine. He has barley there. Go and set it on fire." So Absalom's servants set the property on fire. Then Joab's servants went to Joab with their clothes torn. "Absalom's servants set the property on fire," they said.
References for 2 Samuel 14:30
So Joab went straight to Absalom's house and said to him, "Why have your servants set my property on fire?"
Absalom answered Joab, "Look, I sent you a message: Come here so I can send you to the king to ask, ‘Why have I returned from Geshur? I would be better off if I were still there!' Please let me see the king's face. If I'm guilty, then the king can kill me."
Joab went to the king and reported this to him. Then the king called for Absalom, and Absalom came to the king. He bowed low out of respect, nose to the ground before the king. Then the king kissed Absalom.
