'Armor' in the Bible

But when a stronger man than he attacks and defeats him, the stronger man strips off that man's armor in which he trusted and then divides his plunder.

The night is almost over, and the day is near. Let's therefore put aside the actions of darkness and put on the armor of light.

Put on the whole armor of God so that you may be able to stand firm against the Devil's strategies.

For this reason, take up the whole armor of God so that you may be able to take a stand whenever evil comes. And when you have done everything you could, you will be able to stand firm.
