I. Preparations for the Departure of Israel from Sinai - Numbers 1:1-10:10
Numbering of the People of Israel at Sinai - Numbers 1-4
Four weeks after the erection of the tabernacle (cf. Num 1:1 and Exo 40:17), Moses had the number of the whole congregation taken, by the command of God, according to the families and fathers' houses of the twelve tribes, and a list made of all the males above twenty years of age for service in the army of Jehovah (Num 1:1-3). Nine months before, the numbering of the people had taken place for the purpose of collecting atonement-money from every male of twenty years old upwards (Exo 30:11., compared with Num 38:25-26), and the result was 603,550, the same number as is given here as the sum of all that were mustered in the twelve tribes (Num 1:46). This correspondence in the number of the male population after the lapse of a year is to be explained, as we have already observed at Exo 30:16, simply from the fact that the result of the previous census, which was taken for the purpose of raising head-money from every one who was fit for war, was taken as the basis of the mustering of all who were fit for war, which took place after the erection of the tabernacle; so that, strictly speaking, this mustering merely consisted in the registering of those who had been numbered in the public records, according to their families and fathers' houses. It is most probable, however, that the numbering and registering took place according to the classification adopted at Jethro's suggestion for the administration of justice, viz., in thousands, hundred, fifties, and tens (Exo 18:25), and that the number of men in the different tribes was reckoned in this way simply by thousands, hundreds, and tens-a conclusion which we may draw from the fact, that there are no units given in the case of any of the tribes. On this plan the supernumerary units might be used to balance the changes that had taken place in the actual condition of the families and fathers' houses, between the numbering and the preparation of the muster-rolls, so that the few
