Put on the whole armour of God — The Greek word means a complete suit of armour. Believers are said to put on the girdle, breastplate, shoes; to take the shield of faith, and sword of the Spirit. The whole armour — As if the armour would scarce do, it must be the whole armour. This is repeated, Ephesians 6:13, because of the strength and subtilty of our adversaries, and because of an "evil day" of sore trial being at hand.
