2 Samuel 10:4-5

4So Hanun took hold of David's officers. He cut off half the hair from their beards. He also cut off the lower half of their clothes up to their hips. Then he sent them away.

5Some people told David what had happened. His officers were very ashamed, so David sent a message to them. King David said, ‘Stay in Jericho city until your beards have grown again. Then you can return here.’
