2 Samuel 10:4-5

4So Hanun took David’s servants and shaved off half their beards, and cut off their robes in the middle as far as their hips, and sent them away.

5When David was informed, he sent [messengers] to meet them [before they reached Jerusalem], for the men were greatly ashamed and humiliated. And the king said, “Stay at Jericho until your beards grow, and then return.”
