Numbers 4:5
5. covering veil—the inner veil, which separated the holy from the most holy place. (See on Ex 36:35).
Numbers 4:15
15. the sons of Kohath shall come to bear it, but they shall not touch any holy thing, lest they die—The mode of transport was upon the shoulders of the Levites (see on Nu 7:9), although afterwards wheeled vehicles were employed (2Sa 6:3; 1Ch 15:12). And it was allowed to touch the covering, but not the things covered, on the penalty of death, which was inflicted more than once (1Sa 6:19; 2Sa 6:6, 7). This stern denunciation was designed to inspire a sentiment of deep and habitual reverence in the minds of those who were officially engaged about holy things.
Numbers 7:9
6-9. Moses took the wagons and the oxen—The Hebrew word seems to be fairly rendered by the word "wagons." Wheel carriages of some kind are certainly intended; and as they were covered, the best idea we can form of them is, that they bore some resemblance to our covered wagons. That wheel carriages were anciently used in Egypt, and in what is now Asiatic Turkey, is attested, not only by history, but by existing sculptures and paintings. Some of these the Israelites might have brought with them at their departure; and others, the skilful artisans, who did the mechanical work of the tabernacle, could easily have constructed, according to models with which they had been familiar. Each wagon was drawn by two oxen, and a greater number does not seem to have been employed on any of the different occasions mentioned in Scripture. Oxen seem to have been generally used for draught in ancient times among other nations as well as the Hebrews; and they continue still to be employed in dragging the few carts which are in use in some parts of Western Asia [KITTO].
gave them unto the Levites—The principle of distribution was natural and judicious. The Merarites had twice the number of wagons and oxen appropriated to them that the Gershonites had, obviously because, while the latter had charge only of the coverings and hangings (the light but precious and richly-embroidered drapery, [Nu 4:24-26]) the former were appointed to transport all the heavy and bulky materials (the boards, bars, pillars, and sockets) in short, all the larger articles of furniture [Nu 4:31, 32]. Whoever thinks only of the enormous weight of metal, the gold, silver, brass, &c., that were on the bases, chapiters, and pillars, &c., will probably come to the conclusion that four wagons and eight oxen were not nearly sufficient for the conveyance of so vast a load. Besides, the Merarites were not very numerous, as they amounted only to thirty-two hundred men from thirty years and upward [Nu 4:44]; and, therefore, there is reason to suppose that a much greater number of wagons would afterwards be found necessary, and be furnished, than were given on this occasion [CALMET]. Others, who consider the full number of wagons and oxen to be stated in the sacred record, suppose that the Merarites may have carried many of the smaller things in their hands—the sockets, for instance, which being each a talent weight, was one man's burden (2Ki 5:23). The Kohathites had neither wheeled vehicles nor beasts of burden assigned them, because, being charged with the transport of the furniture belonging to the holy place, the sacred worth and character of the vessels entrusted to them (see on Nu 4:15) demanded a more honorable mode of conveyance. These were carried by those Levites shoulder high. Even in this minute arrangement every reflecting reader will perceive the evidence of divine wisdom and holiness; and a deviation from the prescribed rule of duty led, in one recorded instance, to a manifestation of holy displeasure, calculated to make a salutary and solemn impression (2Sa 6:6-13).Numbers 10:17
13-27. the children of Israel took their journey . . . by the hand of Moses—It is probable that Moses, on the breaking up of the encampment, stationed himself on some eminence to see the ranks defile in order through the embouchure of the mountains. The marching order is described (Nu 2:1-34); but, as the vast horde is represented here in actual migration, let us notice the extraordinary care that was taken for ensuring the safe conveyance of the holy things. In the rear of Judah, which, with the tribes of Issachar and Zebulun, led the van, followed the Gershonites and Merarites with the heavy and coarser materials of the tabernacle. Next in order were set in motion the flank divisions of Reuben and Ephraim. Then came the Kohathites, who occupied the center of the moving mass, bearing the sacred utensils on their shoulder. They were so far behind the other portions of the Levitical body that these would have time at the new encampment to rear the framework of the tabernacle before the Kohathites arrived. Last of all, Dan, with the associated tribes, brought up the rear of the immense caravan. Each tribe was marshalled under its prince or chief and in all their movements rallied around its own standard.
