CHAPTER 1
Numbers 1:1-54 . MOSES NUMBERING THE MEN OF WAR.
1, 2. on the first day of the second month, &c.--Thirteen months had elapsed since the exodus. About one month had been occupied in the journey; and the rest of the period had been passed in encampment among the recesses of Sinai, where the transactions took place, and the laws, religious and civil, were promulgated, which are contained in the two preceding books. As the tabernacle was erected on the first day of the first month, and the order here mentioned was given on the first day of the second, some think the laws in Leviticus were all given in one month. The Israelites having been formed into a separate nation, under the special government of God as their King, it was necessary, before resuming their march towards the promised land, to put them into good order. And accordingly Moses was commissioned, along with Aaron, to take a census of the people. This census was incidentally noticed ( Exodus 38:26 ), in reference to the poll tax for the works of the tabernacle; but it is here described in detail, in order to show the relative increase and military strength of the different tribes. The enumeration was confined to those capable of bearing arms [ Numbers 1:3 ], and it was to be made with a careful distinction of the tribe, family, and household to which every individual belonged. By this rule of summation many important advantages were secured: an exact genealogical register was formed, the relative strength of each tribe was ascertained, and the reason found for arranging the order of precedence in march as well as disposing the different tribes in camp around the tabernacle. The promise of God to Abraham [ Genesis 22:17 ] was seen to be fulfilled in the extraordinary increase of his posterity, and provision made for tracing the regular descent of the Messiah.
3. Aaron shall number them by their armies--or companies. In their departure from Egypt they were divided into five grand companies ( Exodus 13:18 ), but from the sojourn in the wilderness to the passage of the Jordan, they were formed into four great divisions. The latter is here referred to.
4-16. with you there shall be a man of every tribe, &c.--The social condition of the Israelites in the wilderness bore a close resemblance to that of the nomad tribes of the East in the present day. The head of the tribe was a hereditary dignity, vested in the oldest son or some other to whom the right of primogeniture was transferred, and under whom were other inferior heads, also hereditary, among the different branches of the tribe. The Israelites being divided into twelve tribes, there were twelve chiefs appointed to assist in taking the census of the people.
5. these are the names of the men that shall stand with you, &c.--Each is designated by adding the name of the ancestors of his tribe, the people of which were called "Beni-Reuben," "Beni-Levi," sons of Reuben, sons of Levi, according to the custom of the Arabs still, as well as other nations which are divided into clans, as the Macs of Scotland, the Aps of Wales, and the O's and the Fitzes of Ireland [CHALMERS].
16-18. These were the renowned--literally, "the called" of the congregation, summoned by name; and they entered upon the survey the very day the order was given.
18. by their polls--individually, one by one.
19. As the Lord commanded Moses, &c.--The numbering of the people was not an act sinful in itself, as Moses did it by divine appointment; but David incurred guilt by doing it without the authority of God.
