ARMOR
None of the Hebrew words translated “armor” refer definitively to what is currently understood as such.
In one passage it refers to a coat of mail (1 Kings 22:34), in others, to a corselet (2 Chron. 18:33, etc.).
In the NT, “armor” is used symbolically.
(a) “Hopla,” in contrast to the works of darkness, we are to put on the “armor [or weapons] of light” (Rom. 13:12). Paul and his collaborators were accredited as ministers of God by “the weapons of righteousness on the right and on the left” (2 Cor. 6:7).
(b) “Panoply” translates as “full armor.” One stronger than Satan takes away all of his “armor” (Lk. 11:22). The Christian is called to put on “the whole armor of God,” the full panoply of defensive and offensive weapons, so that he can endure on the evil day in his conflict against the spiritual powers of evil in the heavenly places (Eph. 6: 11, 13).
The defensive weapons mentioned in the previous passage are: the breastplate, the sandals, the shield, the helmet; As an offensive weapon, the sword is given.
