'Armor' in the Bible

But when a stronger man attacks and conquers him, he takes away the first man's armor on which the man relied and divides up his plunder.

Clothe yourselves with the full armor of God so that you may be able to stand against the schemes of the devil.

For this reason, take up the full armor of God so that you may be able to stand your ground on the evil day, and having done everything, to stand.
