All that were numbered, &c.— See on Numbers 3:43, The words and Aaron, in this verse, Houbigant remarks, are not found in the Arabic and Syriac; in which omission they agree with the 5th verse, wherein Moses, not Aaron, is commanded to take the number of the tribe of Levi; and also with the 11th, 40th, and 44th verses, in which God speaks to Moses alone; and, lastly, with the 51st verse, which see, with the note on the 14th and 15th verses: and it is observable in the Hebrew copies, that ן ר ואה veaheron, is marked with dots at the top, which is generally supposed to be an index of a false reading; and is one proof of the care of the Jewish transcribers. Kennicott observes, that the word is omitted in the most ancient Hebrew manuscript in the Bodleian library: there are fifteen of these words in the printed Hebrew Bibles which have a dot over every letter; see Kennicott's Dissertation, p. 411. It is said at the close of the verse, that the number of the Levites was 22,000; but the sum total of the preceding numbers, instead of being really 22,000 will be found, upon calling them up, to be 22,300. Dr.
Kennicott solves this difficulty, by observing, that in Numbers 3:22 where the sum of the Gershonites is given, the Hebrew letter ר, 200, should be read, instead of the letter ד, 500. According to this criticism, the sum total of the three numbers exactly answers to what it is said to be in this verse, 22,000: and it is certain that the Hebrew numbers were formerly expressed by letters.
Twenty and two thousand— If the particular numbers mentioned Numbers 3:22; Numbers 3:28; Numbers 3:34 be put together, they make 22,300. But the odd 300 are omitted here, either according to the use of the Holy Scripture, where in so great numbers small sums are commonly neglected, or, because they were the first-born of the Levites, and therefore belonged to God already, and so could not be given to him again instead of the other first-born.
