1 tn Grk “in everything.”
2 sn The Greek word translated shield (θυρεός, qureos) refers to the Roman soldier’s large rectangular wooden shield, called in Latin scutum, about 4 ft (1.2 m) high, covered with leather on the outside. Before a battle in which flaming arrows might be shot at them, the soldiers wet the leather covering with water to extinguish the arrows. The Roman legionaries could close ranks with these shields, the first row holding theirs edge to edge in front, and the rows behind holding the shields above their heads. In this formation they were practically invulnerable to arrows, rocks, and even spears.
3 sn An allusion to Isa 59:17.
4 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]).
5 tn Both “pray” and “be alert” are participles in the Greek text (“praying…being alert”). Both are probably instrumental, loosely connected with all of the preceding instructions. As such, they are not additional commands to do but instead are the means through which the prior instructions are accomplished.
6 tn Grk “and toward it.”
