Adam Clarke Bible Commentary

Much people, even as the sand - This form of speech, by some called a hyperbole, conveys simply the idea of a vast or unusual number - a number of which no regular estimate could be easily formed. Josephus, who seldom finds difficulties in such cases, and makes no scruple of often speaking without book, tells us that the allied armies amounted to 300,000 foot 10,000 horse, and 20,000 chariots of war. Antiq. lib. v., c. 1. That chariots were frequently used in war, all the records of antiquity prove; but it is generally supposed that among the Canaanites they were armed with iron scythes fastened to their poles and to the naves of their wheels. Terrible things are spoken of these, and the havoc made by them when furiously driven among the ranks of infantry. Of what sort the cavalry was, we know not; but from the account here given we may see what great advantages these allies possessed over the Israelites, whose armies consisted of infantry only.
