II Samuel 10:1-8

It happened after this that the king of the people of Ammon died, and Hanun his son reigned in his place. Then David said, “I will show kindness to Hanun the son of Nahash, as his father showed kindness to me.” So David sent by the hand of his servants to comfort him concerning his father. And David’s servants came into the land of the people of Ammon. And the princes of the people of Ammon said to Hanun their lord, “Do you think that David really honors your father because he has sent comforters to you? Has David not rather sent his servants to you to search the city, to spy it out, and to overthrow it?” Therefore Hanun took David’s servants, shaved off half of their beards, cut off their garments in the middle, at their buttocks, and sent them away. When they told David, he sent to meet them, because the men were greatly ashamed. And the king said, “Wait at Jericho until your beards have grown, and then return.” When the people of Ammon saw that they had made themselves repulsive to David, the people of Ammon sent and hired the Syrians of Beth Rehob and the Syrians of Zoba, twenty thousand foot soldiers; and from the king of Maacah one thousand men, and from Ish-Tob twelve thousand men. Now when David heard of it, he sent Joab and all the army of the mighty men. Then the people of Ammon came out and put themselves in battle array at the entrance of the gate. And the Syrians of Zoba, Beth Rehob, Ish-Tob, and Maacah were by themselves in the field.
