Biblical Commentary on the Old Testament

Muster of the Twelve Tribes, with the Exception of that of Levi. - Num 1:1-3. Before the departure of Israel from Sinai, God commanded Moses, on the first of the second month in the second year after the exodus from Egypt, to take the number of the whole congregation of the children of Israel, "according to their families, according to their fathers' houses (see Exo 6:14), in (according to) the number of their names," i.e., each one counted singly and entered, but only "every male according to their heads of twenty years old and upwards" (see Exo 30:14), viz., only צבא כּל־יצא "all who go forth of the army," i.e., all the men capable of bearing arms, because by means of this numbering the tribes and their subdivisions were to be organized as hosts of Jehovah, that the whole congregation might fight as an army for the cause of their Lord (see at Exo 7:4).

Moses and Aaron, who were commanded to number, or rather to muster, the people, were to have with them "a man of every tribe, who was head-man of his fathers' houses," i.e., a tribe-prince, viz., to help them to carry out the mustering. Beth aboth ("fathers' houses"), in Num 1:2, is a technical expression for the subdivisions in which the mishpachoth, or families of the tribes, were arranged, and is applied in Num 1:4 according to its original usage, based upon the natural division of the tribes into mishpachoth and families, to the fathers' houses which every tribe possessed in the family of its first-born. In Num 1:5-15, these heads of tribes were mentioned by name, as in Num 2:3., Num 7:12., Num 10:14. In Num 1:16 they are designated as "called men of the congregation," because they were called to diets of the congregation, as representatives of the tribes, to regulate the affairs of the nation; also "princes of the tribes of their fathers," and "heads of the thousands of Israel:" "prince," from the nobility of their birth; and "heads," as chiefs of the alaphim composing the tribes. Alaphim is equivalent to mishpachoth (cf. Num 10:4; Jos 22:14); because the number of heads of families in the mishpachoth of a tribe might easily amount to a thousand (see at Exo 18:25). In a similar manner, the term "hundred" in the old German came to be used in several different senses (see Grimm, deutsche Rechts-alterthmer, p. 532).

This command was carried out by Moses and Aaron. They took for this purpose the twelve heads of tribes who are pointed out (see at Lev 24:11) by name, and had the whole congregation gathered together by them and enrolled in genealogical tables. התילּד, to announce themselves as born, i.e., to have themselves entered in genealogical registers (books of generations). This entry is called a פּקד, mustering, in Num 1:19, etc. In vv. 20-43 the number is given of those who were mustered of all the different tribes, and in Num 1:44-47 the total of the whole nation, with the exception of the tribe of Levi. "Their generations" (Num 1:20, Num 1:22, Num 1:24, etc.), i.e., those who were begotten by them, so that "the sons of Reuben, Simeon," etc., are mentioned as the fathers from whom the mishpachoth and fathers' houses had sprung. The ל before שׁמעון בּני in Num 1:22, and the following names (in Num 1:24, Num 1:26, etc.), signifies "with regard to" (as in Isa 32:1; Psa 17:4, etc.).

Moses was not to muster the tribe of Levi along with the children of Israel, i.e., with the other tribes, or take their number, but to appoint the Levites for the service of the dwelling of the testimony (Exo 38:21), i.e., of the tabernacle, that they might encamp around it, might take it down when the camp was broken up, and set it up when Israel encamped again, and that no stranger (zar, non-Levite, as in Lev 22:10) might come near it and be put to death (see Num 3:10). The rest of the tribes were to encamp every man in his place of encampment, and by his banner (see at Num 2:2), in their hosts (see Num 2), that wrath might not come upon the congregation, viz., through the approach of a stranger. קצף, the wrath of Jehovah, breaking in judgment upon the unholy who approached His sanctuary in opposition to His command (Num 8:19; Num 18:5, Num 18:22). On the expression "keep the charge" (shamar mishmereth), see at Gen 26:5 and Lev 8:35.
