The order to “stand” that pervades Ephesians 6:11–14 does not imply that Christian soldiers are given a special tactic by which they are able to defend themselves, but rather teaches them that the battle is the Lord’s. They are to stand back and watch him win the victory for them (cf. הִֽתְיַצְב֗וּ, “stand firm!” in Ex 14:13 in the context of Ex 14:13–14, 30–31; and הִתְיַצְּב֣וּ עִמְד֡וּ, “stand firm! stand!” in 2 Chr 20:17).
