Ephesians 6:17

And take the helmet of salvation ¹  and the sword ²  of the Spirit, which is the word of God.

1Sa 17:5,58; Isa 49:2; Isa 59:17; Mt 4:4,7,10,11; 1Th 5:8; Heb 4:12; Heb 12:5,6; Heb 13:5,6; Re 1:16; Re 2:16; Re 12:11; Re 19:15

¹ sn An allusion to Isa 59:17.

² sn The Greek term translated sword (μάχαιρα, macaira) refers to the Roman gladius, a short sword about 2 ft (60 cm) long, used for close hand-to-hand combat. This is the only clearly offensive weapon in the list of armor mentioned by the author (he does not, for example, mention the lance [Latin pilum]).
