2 Samuel 10:2

1And it came to pass after this, that the king of the children of Ammon died, and Hanun his son reigned in his stead.

2Then said David, I will shew kindness unto Hanun the son of Nahash, as his father shewed kindness unto me. And David sent to comfort him by the hand of his servants for his father. And David’s servants came into the land of the children of Ammon.

3And the princes of the children of Ammon said unto Hanun their lord, Thinkest thou that David doth honour thy father, that he hath sent comforters unto thee? hath not David rather sent his servants unto thee, to search the city, and to spy it out, and to overthrow it?

4Wherefore Hanun took David’s servants, and shaved off the one half of their beards, and cut off their garments in the middle, even to their buttocks, and sent them away.
