'Helmets' in the Bible

Uzziah supplied shields, spears, helmets, breastplates, bows, and slingstones for the entire army.

Harness the horses to the chariots! Mount your horses! Put on your helmets and take your positions! Sharpen you spears! Put on your armor!

They will attack you with weapons, chariots, wagons, and with a huge army; they will array themselves against you on every side with large shields, small shields, and helmets. I will assign them the task of judgment; they will punish you according to their laws.

Persia, Ethiopia, and Put are with them, all of them with shields and helmets.
