And Moses and Aaron and the chief of the congregation numbered the sons of the Kohathites after their families, and after the house of their fathers,

Jamieson-Fausset-Brown Bible Commentary

34-49. Moses and Aaron and the chief of the congregation numbered the sons of the Kohathites, &c.-This enumeration was made on a different principle from that which is recorded in the preceding chapter [Nu 3:15]. That was confined to the males from a month old and upward, while this was extended to all capable of service in the three classes of the Levitical tribe. In considering their relative numbers, the wisdom of Divine Providence appears in arranging that, whereas in the Kohathites and Gershonites, whose burdens were few and easier, there were but about a third part of them which were fit for service; the Merarites, whose burdens were more and heavier, had above one half of them fit for this work [Poole]. The small population of this tribe, so inferior to that of the other tribes, is attempted to be explained (see on [61]Nu 3:39).

Matthew Henry's Concise Commentary

4:34-49 God so ordered it, that though the Merarites were the fewest in number, yet they should have most able men among them; for whatever service God calls men to, he will furnish them for it, give strength in proportion to the work, and grace sufficient. The least of the tribes had many more able men than the Levites: those who engage in the service of this world, are many more than those devoted to the service of God. May our souls be wholly devoted to his service.

Matthew Henry's Whole Bible Commentary

Verses 34-49

We have here a particular account of the numbers of the three families of the Levites respectively, that is, of the effective men, between thirty years old and fifty. Observe, 1. The Kohathites were, in all, 8600 from a month old and upwards; but of these there were but 2750 serviceable men, not a third part. The Gershonites, in all, 7500, and of them but 2630 serviceable men, little more than a third part. Note, Of the many that add to the numbers of the church, there are comparatively but few that contribute to the service of it. So it has been, and so it is; many have a place in the tabernacle that do but little of the work of the tabernacle, Phil. 2:20, 21. 2. That the Merarites were but 6200 in all, and yet of these there were 3200 serviceable men, that is, more than half. The greatest burden lay upon that family, the boards, and pillars, and sockets; and God so ordered it that, though they were the fewest in number, yet they should have the most able men among them; for whatever service God calls men to he will furnish them for it, and give strength in proportion to the work, grace sufficient. 3. The whole number of the able men of the tribe of Levi who entered into God's host to war his warfare was but 8580, whereas the able men of the other tribes that entered into the host of Israel to war their warfare were many more. The least of the tribes had almost four times as many able men as the Levites, and some of them more than eight times as many; for those that are engaged in the service of this world, and war after the flesh, are many more than those that are devoted to the service of God, and fight the good fight of faith.
