2 Samuel 10:4

Wherefore Hanun, listening to the counsel of his princes, especially as this implied a criticism of his carelessness, took David's servants and shaved off the one half of their beards, the one side, one of the grossest insults that can be offered an Oriental, who considers his beard the sign of manly dignity and freedom, and cut off their garments in the middle, even to their buttocks, thus exposing them before the eyes of all men, and sent them away, heaped with this double insult and disgrace.
