Shaved off the one half of their beards - The beard is held in high respect in the East: the possessor considers it his greatest ornament; often swears by it; and, in matters of great importance, pledges it. Nothing can be more secure than a pledge of this kind; its owner will redeem it at the hazard of his life. The beard was never cut off but in mourning, or as a sign of slavery. Cutting off half of the beard and the clothes rendered the men ridiculous, and made them look like slaves: what was done to these men was an accumulation of insult.
In 1 Chronicles 19:4, more concisely “shaved.” Cutting off a person‘s beard is regarded by the Arabs as an indignity equal to flogging and branding among ourselves. The loss of their long garments, so essential to Oriental dignity, was no less insulting than that of their beards.
