1 Chronicles 19:2-5

2David thought, “I will show kindness to Hanun son of Nahash, because his father showed kindness to me.” So David sent a delegation to express his sympathy to Hanun concerning his father. When David’s envoys came to Hanun in the land of the Ammonites to express sympathy to him,

3the Ammonite commanders said to Hanun, “Do you think David is honoring your father by sending envoys to you to express sympathy? Haven’t his envoys come to you only to explore and spy out the country and overthrow it?”

4So Hanun seized David’s envoys, shaved them, cut off their garments at the buttocks, and sent them away.

5When someone came and told David about the men, he sent messengers to meet them, for they were greatly humiliated. The king said, “Stay at Jericho till your beards have grown, and then come back.”
