Ezekiel 38:3-4

38:3 and say: ‘This is what the sovereign Lord says: Look, I am against you, Gog, chief prince of Meshech and Tubal. 38:4 I will turn you around, put hooks into your jaws, and bring you out with all your army, horses and horsemen, all of them fully armed, a great company with shields of different types, all of them armed with swords.

tn Or “I challenge you.” The phrase “I am against you” may be a formula for challenging someone to combat or a duel. See D. I. Block, Ezekiel (NICOT), 1:201-2, and P. Humbert, “Die Herausforderungsformel ‘h!nn#n' ?l?K>,’” ZAW 45 (1933): 101-8.

sn The Hebrew text mentions two different types of shields here.
