What does Isaiah 3:20 mean?

The different kinds of adornments that the Lord will take away from the prideful women of Judah (Isaiah 3:18–19, 21–24) is continued in this verse. These are women who have rejected God while displaying their wealth and likely their allegiance to false gods on their person (Isaiah 3:16–17). The Lord will no longer allow these women to adorn themselves this way.

A headdress was likely a circlet of gold or silver worn on the head, or it may be a kind of turban. The word for "armlets" refers to bracelets worn above the elbow, but the same word may also be translated as "ankle chains." These were connected links worn between the ankles that would require the wearer to take small delicate steps (Isaiah 3:16). The word for "perfume boxes" literally means "houses of breath" or, suggesting occult practices, "houses of the soul." Amulets may be charms worn for good luck or to ward off evil spirits (Isaiah 3:3).

These women were apparently displaying their allegiance and dependence on false gods through the items they were wearing on their bodies. The Lord would not allow them to continue to believe that their charms and gods were providing for and protecting them.
