thirty: Thirty-two thousand soldiers, exclusive of the thousand sent by the king of Maachah, are mentioned in the parallel passage (2 Samuel 10:6); but of chariots or cavalry there is no mention; and the number of chariots stated here is prodigious, and beyond all credibility. But as the word raichev: denotes not only a chariot, but a rider (see Isaiah 21:7), it ought most probably to be rendered here, in a collective sense, cavalry; and then the number of troops will exactly agree with the passage in Samuel. It is probable that they were a kind of auxiliary troops who were usually mounted on horses, or in chariots, but who occasionally served as foot-soldiers.
the king of Maachah: This variation exists only in the translation, the original being the same in both places, melech maachah:, "the king of Maachah." 2 Samuel 10:6, king Maachah
