Exodus 14:7

Captains. Septuagint, "Tristatas." Three men rode on every chariot, which was armed with scythes, to cut down all that came within contact, the chief warrior, with his armour bearer and charioteer. (St. Gregory of Nyssa) (Haydock) --- Or these three captains may very probably be the three chief officers of state, (Calmet) or the generals of cavalry, and of infantry, and the chief treasurer, or receiver of taxes, principes equitum peditumque erant, & tributorum. (St. Jerome)
