2 Samuel 10:2-7
English Standard Version
Chapter 10
2And David said, "I will deal loyally with Hanun the son of Nahash, as his father dealt loyally with me." So David sent by his servants to console him concerning his father. And David 's servants came into the land of the Ammonites. 3But the princes of the Ammonites said to Hanun their lord, "Do you think, because David has sent comforters to you, that he is honoring your father? Has not David sent his servants to you to search the city and to spy it out and to overthrow it?" 4So Hanun took David 's servants and shaved off half the beard of each and cut off their garments in the middle, at their hips, and sent them away. 5When it was told David, he sent to meet them, for the men were greatly ashamed. And the king said, "Remain at Jericho until your beards have grown and then return."
6When the Ammonites saw that they had become a stench to David, the Ammonites sent and hired the Syrians of Beth-rehob, and the Syrians of Zobah, 20,000 foot soldiers, and the king of Maacah with 1,000 men, and the men of Tob, 12,000 men.
7And when David heard of it, he sent Joab and all the host of the mighty men.
