2 Samuel 14:28-30

So Absalom dwelt two full years in Jerusalem, and saw not the king's face. Therefore Absalom sent for Joab, to have sent him to the king; but he would not come to him: and when he sent again the second time, he would not come. Therefore he said unto his servants, See, Joab's field is near mine, and he hath barley there; go and set it on fire. And Absalom's servants set the field on fire.
