Their ancient way of fighting was with chariots and bows; the prophet calls, in the name of the commanders of the Egyptian armies, to the horses and chariots to come on, and engage in the fight. The Ethiopians were the Cushites, who were neighbours to the Egyptians, so were the Libyans; both of them it should seem were famous for handling the shield: the Libyans were descended from Phut; both the Cushites and the Phutites or Libyans were descended from Ham, Genesis 10:6. The Lydians were as famous for the use of the bow in war; they were descended from Mizraim or Shem, Genesis 10:13,22: the Lydians here meant are thought to be those descended from Mizraim, and some think these were Ethiopians. They were all auxiliaries to the Egyptians in this expedition.
