Exodus 14:7

Six hundred chosen chariots, etc. - According to the most authentic accounts we have of war-chariots, they were frequently drawn by two or by four horses, and carried three persons: one was charioteer, whose business it was to guide the horses, but he seldom fought; the second chiefly defended the charioteer; and the third alone was properly the combatant. It appears that in this case Pharaoh had collected all the cavalry of Egypt; (see Exodus 14:17); and though these might not have been very numerous, yet, humanly speaking, they might easily overcome the unarmed and encumbered Israelites, who could not be supposed to be able to make any resistance against cavalry and war-chariots.

Six hundred chosen chariots - The Egyptian army comprised large numbers of chariots, each drawn by two horses, with two men, one bearing the shield and driving, the other fully armed. The horses were thoroughbred, renowned for strength and spirit. Chariots are first represented on the monuments of the 18th dynasty. By "all the chariots of Egypt" we are to understand all that were stationed in Lower Egypt, most of them probably at Rameses and other frontier garrisons near the headquarters of Pharaoh.

Captains - The word שׁלישׁ shâlı̂ysh, literally "third or thirtieth," may represent an Egyptian title. The king had about him a council of thirty, each of whom bore a title, Mapu, a "thirty man." The word occurs frequently in the Books of Kings. David seems to have organized the Shalishim as a distinct corps (see 2 Samuel 23:8 Hebrew), retaining the old name, and adopting the Egyptian system.

14:7 Captains over every one of them - Or rather over all of them; distributing the command of them to his several Captains.
