'Crescent shaped' in the Bible

Then Zebah and Zalmunna responded, "Get up and attack us yourself, since a man's valor is only as good as the man himself." So Gideon got up, killed Zebah and Zalmunna, and took away the crescent-shaped necklaces that adorned the necks of their camels.

The weight of the rings that he had asked for was 1,700 gold coins, not counting the crescent-shaped necklaces, pendants, and purple garments worn by the Midian kings, and also not counting the bands adorning the necks of their camels.
