1 Chronicles 19:1, David’s messengers, sent to comfort Hanun, the son of Nahash, are villainously treated; 1 Chronicles 19:6, The Ammonites, strengthened by the Syrians, are overcome by Joab and Abishai; 1 Chronicles 19:16, Shophach, making a new supply of the Syrians, is slain by David.

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

Abishai: Heb. Abshai, 1 Chronicles 11:20, 1 Chronicles 18:12, The variation of אבישי [Strong's H52], Abishai, and אבשי [Strong's H52], Abshai, is simply caused by the elision of י, yood, which is by no means uncommon.
and they set: 1 Chronicles 19:9

of good: Deuteronomy 31:6, Deuteronomy 31:7, Joshua 1:7, Joshua 10:25, 1 Samuel 4:9, 1 Samuel 14:6-12, 1 Samuel 17:32, 2 Samuel 10:12, Ezra 10:4, Nehemiah 4:14, Psalms 27:14, 1 Corinthians 16:13

Shophach: This variation arises from the permutation of ב, baith, and פ, pay; being written in the parallel passage שובך [Strong's H7731], Shobach, and here שופך [Strong's H7780], Shophach 2 Samuel 10:16, Shobach.

upon them: Instead of alaihem, "upon them," it is in 2 Samuel 10:17 chelamah, "to Helam:" the one seems evidently to be a mistake for the other.
and set: 1 Chronicles 19:9, Isaiah 22:6-7

fled before Israel: 1 Chronicles 19:13-14, Psalms 18:32, Psalms 33:16, Psalms 46:11
seven thousand: In the parallel passage, "the men of seven hundred chariots;" which difference probably arose from mistaking ן, noon final, which stands for 700, for ז, zayin, with a dot above, which denotes 7,000, or vice versa: the great similarity of these letters might easily cause the one to be mistaken for the other.
footmen: If these troops were as we have suppose, a kind of dismounted cavalry, the terms footmen and horsemen might be indifferently applied to them. 2 Samuel 10:18, horsemen
