NET Notes: Eph 6:17

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]).
