2 Samuel 10:4-5

4So Hanun seized David’s servants and shaved off half of each one’s beard. He cut the lower part of their robes off so that their buttocks were exposed, and then sent them away.

5Messengers told David what had happened, so he summoned them, for the men were thoroughly humiliated. The king said, “Stay in Jericho until your beards have grown again; then you may come back.”
