2 Samuel 10:4-5

King James Version

⁴ Wherefore 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.

⁵ When they told it unto David, he sent to meet them, because the men were greatly ashamed: and the king said, Tarry at Jericho until your beards be grown, and then return.
