3 the princes of the Ammonites said to Hanun their lord, "Do you think that David is honoring your father because he has sent consolers to you? aHas David not sent his servants to you in order to search the city, to spy it out and overthrow it?"
4 So Hanun took David's servants and ashaved off half of their beards, and bcut off their garments in the middle as far as their hips, and sent them away.
5 When they told it to David, he sent to meet them, for the men were greatly humiliated. And the king said, "Stay at Jericho until your beards grow, and then return."
