Verse 28. - Eight thousand and six hundred. The four families of the Kohathites, of which that of Amram was one, must have contained about 18,000 souls. Moses and Aaron were sons of Amram, and they seem to have had but two sons apiece at this time. If, therefore, the family of the Amramites was at all equal in numbers to the other three, they must have had more than 4000 brothers and sisters, nephews and nieces. It is urged in reply that Amram lived 137 years, and may have had many other children, and that the variations in the comparative rates of increase are so great and so unaccountable that it is useless to speculate upon them. There is, however, a more serious difficulty connected with the genealogy of Moses and Aaron, as given here and elsewhere. If they were the great-grandchildren of Levi on their father's side, and his grandchildren on their mother's side, it is impossible to maintain the obvious meaning of Exodus 12:40. Either the genealogy must be lengthened, or the time must be very much shortened for the sojourning in Egypt. The known and undoubted habit of the sacred writers to omit names in their genealogies, even in those which seem most precise, lessens the difficulty of the first alternative, whereas every consideration of numbers, including those in this passage, increases the difficulty of the second. To endeavour to avoid either alternative, and to force the apparent statements of Scripture into accord by assuming a multiplicity of unrecorded and improbable miracles at every turn (as, e.g., that Jochebed, the mother of Moses, was restored to youth and beauty at an extreme old age), is to expose the holy writings to contempt. It is much more reverent to believe, either that the genealogies are very imperfect, or that the numbers in the text have been very considerably altered. Every consideration of particular examples, still more the general impression left by the whole narrative, favours the former as against the latter alternative.

3:14-39 The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.In the number of all the males, from a month old and upwards, were eight thousand and six hundred,.... 8,600 men, which was the largest number of any of the houses of the Levites; but considering it had double the number of families in it, the increase was not so large in proportion, at least to Gershon, whose two families wanted but 1,100 of these four:

keeping the charge of the sanctuary; of the holy and most holy places, and the vessels and instruments belonging thereunto; not that the males of a month old were keeping them, but when they were grown up and were capable of it, they had the charge thereof, in which they were instructed and trained up from their youth.
