For the protection of the head, as worn by warriors. See ARMOR. In the Christian’s armor the helmet is “salvation,” or “the hope of salvation” (Eph. 6:17; 1 Thess. 5:8). It is those who know their salvation that can take part against the wicked spirits in the heavenlies. It is to be remarked that Jehovah (Christ) in a future day will Himself put on righteousness as a breastplate, and a helmet of salvation, to avenge His people by punishing their enemies (Isa. 59:17).
