Ephesians 6:11
10 Finally, be strengthened in the Lord and in the strength of his power. 11 Clothe yourselves with the full armor of God, so that you will be able to stand against the schemes of the devil. 12 For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world rulers of this darkness, against the spiritual forces of evil in the heavens. 13 For this reason, take up the full armor of God so that you may be able to stand your ground on the evil day, and having done everything, to stand. 14 Stand firm therefore, by fastening the belt of truth around your waist, by putting on the breastplate of righteousness,
4 Maccabees 13:16
13 Each of them and all of them together looking at one another, cheerful and undaunted, said, "Let us with all our hearts consecrate ourselves to God, who gave us our lives, and let us use our bodies as a bulwark for the law. 14 Let us not fear him who thinks he is killing us, 15 for great is the struggle of the soul and the danger of eternal torment lying before those who transgress the commandment of God. 16 Therefore let us put on the full armor of self-control, which is divine reason. 17 For if we so die, Abraham and Isaac and Jacob will welcome us, and all the fathers will praise us." 18 Those who were left behind said to each of the brothers who were being dragged away, "Do not put us to shame, brother, or betray the brothers who have died before us."
Notes and References
"... The clothing metaphor itself is, of course, not Hermas’s creation. It became particularly prominent among the philosophers, mystery cults, gnostic sources, and Jewish and other Christian literature of our period.154 In fact, the metaphor’s ubiquity makes it virtually impossible to determine its origins. It appeared, for example, among the earliest Greek authors and even before that in Sumerian sources too. We find it scattered throughout Jewish scripture; non-Pauline literature ultimately included in the New Testament also attests it ... Like so many authors before them, both the apostle and his pseudepigraphers frequently use the metaphor throughout their letters, but they do so in telling ways.159 Using forms of ἐνδύειν and its compound ἐπενδύειν, they deploy it to describe putting on Christ in baptism (Rom 13:14, Gal 3:27); the imperishable resurrection body (1 Cor 15:49–54; 2 Cor 5:1–4); various virtues (Colossians 3:12); spiritual armor (Romans 13:12, Ephesians 6:11, 14, and 1 Thessalonians 5:8); and a new person (Ephesians 4:22–24, Colossians 3:9–10) ..."
