In that day the Lord will take away their finery: the ankle bracelets, the headbands, the crescent necklaces, Bible other translations

“the crescent necklaces.” Crescent shaped ornaments, like the crescent moon, were used in ancient times to ward off evil spirits. It was quite common for women, especially young women, to wear the crescent moon as an apotropaic amulet to provide protection from evil and evil spirits, which is why it is mentioned here in Isaiah 3:18 as an ornament worn by women. Sometimes the crescent moon was also put on camels (see commentary on Judg. 8:21).
