'Armor' in the Bible

But when someone stronger attacks him and overcomes him, he takes from him his whole armor in which he trusted, and divides his spoils.

The night is far gone, and the day is near. Let's therefore throw off the works of darkness, and let's 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 you may be able to stand against the wiles of the devil.

Therefore, put on the whole armor of God, that you may be able to withstand in the evil day, and, having done all, to stand.
