Numbers 3:1

Muster of the Tribe of Levi. - As Jacob had adopted the two sons of Joseph as his own sons, and thus promoted them to the rank of heads of tribes, the tribe of Levi formed, strictly speaking, the thirteenth tribe of the whole nation, and was excepted from the muster of the twelve tribes who were destined to form the army of Jehovah, because God had chosen it for the service of the sanctuary. Out of this tribe God had not only called Moses to be the deliverer, lawgiver, and leader of His people, but Moses' brother Aaron, with the sons of the latter, to be the custodians of the sanctuary. And now, lastly, the whole tribe was chosen, in the place of the first-born of all the tribes, to assist the priests in performing the duties of the sanctuary, and was numbered and mustered for this its special calling. Num 3:1 In order to indicate at the very outset the position which the Levites were to occupy in relation to the priests (viz., Aaron and his descendants), the account of their muster commences not only with the enumeration of the sons of Aaron who were chosen as priests (Num 3:2-4), but with the heading: "These are the generations of Aaron and Moses in the day (i.e., at the time) when Jehovah spake with Moses in Mount Sinai (Num 3:1). The toledoth (see at Gen 2:4) of Moses and Aaron are not only the families which sprang from Aaron and Moses, but the Levitical families generally, which were named after Aaron and Moses, because they were both of them raised into the position of heads or spiritual fathers of the whole tribe, namely, at the time when God spoke to Moses upon Sinai. Understood in this way, the notice as to the time is neither a superfluous repetition, nor introduced with reference to the subsequent numbering of the people in the steppes of Moab (Num 26:57.).…

Here, I. The family of Aaron is confirmed in the priests' office, Num 3:10. They had been called to it before, and consecrated; here they are appointed to wait on their priests' office: the apostle uses this phrase (Rom 12:7), Let us wait on our ministry. The office of the ministry requires a constant attendance and great diligence; so frequent are the returns of its work, and yet so transient its favourable opportunities, that it must be waited on. Here is repeated what was said before (Num 1:51): The stranger that cometh nigh shall be put to death, which forbids the invading of the priest's office by any other person whatsoever; none must come nigh to minister but Aaron and his sons only, all others are strangers. It also lays a charge on the priests, as door-keepers in God's house, to take care that none should come near who were forbidden by the law; they must keep off all intruders, whose approach would be to the profanation of the holy things, telling them that if they came near it was at their peril, they would die by the hand of God, as Uzza did. The Jews say that afterwards there was hung over the door of the temple a golden sword (perhaps alluding to that flaming sword at the entrance of the garden of Eden), on which was engraven, The stranger that cometh nigh shall be put to death. II. A particular account is given of this family of Aaron; what we have met with before concerning them is here repeated. 1. The consecration of the sons of Aaron, Num 3:3. They were all anointed to minister before the Lord, though it appeared afterwards, and God knew it, that two of them were wise and two were foolish. 2. The fall of the two elder (Num 3:4): they offered strange fire, and died for so doing, before the Lord. This is mentioned here in the preamble to the law concern…

3:1–4:49 The duties of Israel’s priests and Levites included the transportation, assembly, safety, and upkeep of the Tabernacle. The physical arrangement of Israel’s tribes reflected concern for these activities. 3:1-4 The family line of Aaron provided the professional priests who led Israel’s worship. Aaron’s four sons were the foundation of Israel’s priesthood; they stood in God’s presence and served him on behalf of the people. They were appointed to lead the people and serve the Lord as ministers in the Tabernacle and as guardians of God’s covenant with his people.
