2 Samuel 10:18 - Clarke's commentary and critical notes on the Bible

And the Syrians fled before Israel; and David slew the men of seven hundred chariots of the Syrians, and forty thousand horsemen, and smote Shobach the captain of their host, who died there. Seven Hundred chariots - and forty thousand Horsemen - In the parallel place, 1 Chronicles 19:18, it is said, David slew of the Syrians Seven Thousand men, which fought in chariots. It is difficult to ascertain the right number in this and similar places. It is very probable that, in former times, the Jews expressed, as they often do now, their numbers, not by words at full length, but by numeral letters; and, as many of the letters bear a great similarity to each other, mistakes might easily creep in when the numeral letters came to be expressed by words at full length. This alone will account for the many mistakes which we find in the numbers in these books, and renders a mistake here very probable. The letter ז zain, with a dot above, stands for seven thousand, נ nun for seven hundred: the great similarity of these letters might easily cause the one to be mistaken for the other, and so produce an error in this place.
