'Armor' in the Bible

Now all the Moabites heard that the kings had come up to fight against them. And all who were able to put on armor and older were summoned and stood on the border.

Hezekiah listened to them, and showed them all his treasure house, the silver and the gold and the spices and the precious oil and the house of his armor and all that was found in his treasuries. There was nothing in his house nor in all his dominion that Hezekiah did not show them.
