1 Thessalonians 5:8

Putting on the breastplate of faith and love (endusamenoi qwraka pistew kai agaph). First aorist (ingressive) middle participle of enduw. The same figure of breastplate in Ephesians 6:14 , only there "of righteousness." The idea of watchfulness brings the figure of a sentry on guard and armed to Paul's mind as in Romans 13:12 "the weapons of light." The word qwrax (breastplate) is common in the LXX. For a helmet, the hope of salvation (perikepalaian elpida swthria). Same figure in Ephesians 6:17 and both like Isaiah 59:17 . Late word meaning around (peri) the head (kepalh) and in Polybius, LXX, and in the papyri. Swthria is objective genitive.
