1 Chronicles 19:1-4

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

2And David said, I will shew kindness unto Hanun the son of Nahash, because his father shewed kindness to me. So David sent messengers to comfort him concerning his father. And David’s servants came into the land of the children of Ammon to Hanun, to comfort him.

3But the princes of the children of Ammon said to Hanun, Thinkest thou that David doth honour thy father, that he hath sent comforters unto thee? are not his servants come unto thee for 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, even to their buttocks, and sent them away.
