Charles Ellicott Commentary Judges 8:21

"Then Zebah and Zalmunna said, Rise thou, and fall upon us; for as the man is, so is his strength. And Gideon arose, and slew Zebah and Zalmunna, and took the crescents that were on their camels` necks." — Judges 8:21 (ASV)

Rise thou, and fall upon us. —They sought to avoid the pain and shame of falling by the irresolute hands of a boy.

For as the man ... his strength. —Deuteronomy 33:25. As thy days, so shall thy strength be.

Ornaments. — Saharonim, “little moons,” crescent-shaped ornaments of gold and silver, still in common use to decorate animals. Isaiah 3:18, round tires like the moon. “Niveo lunata monilia dente” (Stat. Theb. ix. 689). After one of his battles Mohammed found a slain camel adorned with these lunulœ and with strings of emeralds. The Roman senators (for another reason) wore silver crescents on their shoes.
