'Armor' in the Bible

But when a stronger man attacks him [and] conquers him, he takes away his full armor in which he trusted and distributes his plunder.

Put on the full armor of God, so that you may be able to stand against the stratagems of the devil,

Because of this, take up the full armor of God, in order that you may be able to resist in the evil day, and having done everything, to stand.
