“Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.”
King James Version (KJV)
6:11 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, ver.#13|, because of the strength and subtilty of our adversaries, and because of an evil day of sore trial being at hand.
Eph 6:11 Put on the whole armour of God. The ancient soldier was not equipped for war until he had put on his armor. Paul was at that time a prisoner, probably living near the praetorian camp in Rome, as he was by the Roman customs under the charge of the praetorian prefect. It is possible that the figure was suggested by the sights he so often witnessed. See PNT "1Th 5:8". That ye may be able to stand against the wiles of the devil. The great enemy. The armor was designed not only to protect, but there were weapons also with which to assail him.
