'Armor' in the Bible

but when a stronger than he shall come upon him, and overcome him, he taketh from him his whole armor wherein he trusted, and divideth his spoils.

The night is far spent, and the day is at hand: let us therefore cast off the works of darkness, and let us put on the armor of light.

in the word of truth, in the power of God; by the armor of righteousness on the right hand and on the left,

Put on the whole armor of God, that ye may be able to stand against the wiles of the devil.

Wherefore take up the whole armor of God, that ye may be able to withstand in the evil day, and, having done all, to stand.
