2 Samuel 14:28-30

And Absalom dwelt two full years in Jerusalem; and he saw not the king’s face. Then Absalom sent for Joab, to send him to the king; but he would not come to him: and he sent again a second time, but 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.
