1 Chronicles 19:4
“Wherefore Hanun took David’s servants, and shaved them, and cut off their garments in the midst hard by their buttocks, and sent them away.”
And David said, I will shew kindness unto Hanun the son of Nahash, because his father shewed kindness to me. And David sent messengers to comfort him concerning his father. So the servants of David came into the land of the children of Ammon to Hanun, to comfort him.
But 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?
Wherefore Hanun took David’s servants, and shaved them, and cut off their garments in the midst hard by their buttocks, and sent them away.
Then there went certain, and told David how the men were served. And he sent to meet them: for the men were greatly ashamed. And the king said, Tarry at Jericho until your beards be grown, and then return.
And when the children of Ammon saw that they had made themselves odious to David, Hanun and the children of Ammon sent a thousand talents of silver to hire them chariots and horsemen out of Mesopotamia, and out of Syria–maachah, and out of Zobah.
