2 Samuel 10:4-5
4 So Hanun seized David’s men, shaved off half of each man’s beard, cut off their garments in the middle at the buttocks, and sent them away.
5 When David was told about this, he sent messengers to meet the men, for they were greatly humiliated. The king said, “Stay at Jericho till your beards have grown, and then come back.”
