Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
Deuteronomy 20:3-4
And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them; For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you.
Paul's armour-of-God passage frames the believer's spiritual warfare within the Deuteronomic holy war statute. The Deuteronomy 20 priest's exhortation before battle establishes the covenant warrior's posture: do not fear, do not tremble, for the LORD goes with you. Paul's 'stand therefore' command mirrors the military standing posture required of the covenant warrior, and his enumeration of spiritual armour translates the Mosaic holy war framework into the domain of spiritual engagement. The 'Stand' command echoes the Deuteronomic 'ye approach this day unto battle' — the same covenant-warrior positioning, now applied to the cosmic conflict.
