1 Chronicles 19:2-5

2Then David said, “I will show kindness to Hanun the son of Nahash, because his father showed kindness to me.” So David sent messengers to console him concerning his father. And David’s servants came into the land of the sons of Ammon to Hanun to console him. 3But the princes of the sons of Ammon said to Hanun, “1Do you think that David is honoring your father, in that he has sent comforters to you? Have not his servants come to you to search and to overthrow and to spy out the land?” 4So Hanun took David’s servants and shaved them and cut off their garments in the middle as far as their hips, and sent them away. 5Then certain persons went and told David about the men. And he sent to meet them, for the men were greatly humiliated. And the king said, “2Stay at Jericho until your beards grow, and then return.”
