On Numbers 3:1

These also are the generations of Aaron and Moses,.... The descendants of them, those of the former, who is named first, because the eldest, were priests, and those of the latter Levites, and who are not very plainly pointed at, but are included among the Amramites, Numbers 3:27; the posterity of Moses being very obscure, only Levites, and these not particularly named but swallowed up among the Kohathites: find the following account was as it stood:

in the day that the Lord spoke with Moses in mount Sinai; and not, altogether as it then, was when he spoke to him in the wilderness, of Sinai, for then Aaron had four sons, but now two of them were dead as is after observed; and it seems to be for the sake of this circumstance chiefly that this clause is so put.

Keil & Delitzsch

On Numbers 3:1-4

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.). Aaron is placed before Moses here (see at Exo 6:26.), not merely as being the elder of the two, but because his sons received the priesthood, whilst the sons of Moses, on the contrary, were classed among the rest of the Levitical families (cf. Ch1 23:14).

Num 3:2-4

Names of the sons of Aaron, the "anointed priests (see Lev 8:12), whose hand they filled to be priests," i.e., who were appointed to the priesthood (see at Lev 7:37). On Nadab and Abihu, see Lev 10:1-2. As they had neither of them any children when they were put to death, Eleazar and Ithamar were the only priests "in the sight of Aaron their father," i.e., during his lifetime. "In the sight of:" as in Gen 11:28.

Matthew Henry

On Numbers 3:1-13

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 concerning the priesthood, for a warning to all succeeding priests; let them know, by this example, that God is a jealous God, and will not be mocked; the holy anointing oil was an honour to the obedient, but not a shelter to the disobedient. It is here said, They had no children, Providence so ordering it, for their greater punishment, that none of their descendants should remain to be priests, and so bear up their name who had profaned God's name. 3. The continuance of the two younger: Eleazar and Ithamar ministered in the sight of Aaron. It intimates, (1.) The care they took about their ministration not to make any blunders; they kept under their father's eye, and took instruction from him in all they did, because, probably, Nadab and Abihu got out of their father's sight when they offered strange fire. Note, It is good for young people to act under the direction and inspection of those that are aged and experienced. (2.) The comfort Aaron took in it; it pleased him to see his younger sons behave themselves prudently and gravely, when his two elder had miscarried. Note, It is a great satisfaction to parents to see their children walk in the truth, Jo3 1:4.

III. A grant is made of the Levites to be assistants to the priests in their work: Give the Levites to Aaron, Num 3:9. Aaron was to have a greater propriety in, and power over, the tribe of Levi than any other of the prices had in and over their respective tribes. There was a great deal of work belonging to the priests' office, and there were now only three pairs of hands to do it all, Aaron's and his two sons'; for it does not appear that they had either of them any children at this time, at least not any that were of age to minister, therefore God appoints the Levites to attend upon them. Note, Those whom God finds work for his will find help for. Here is, 1. The service for which the Levites were designed: they were to minister to the priests in their ministration to the Lord (Num 3:6), and to keep Aaron's charge (Num 3:7), as the deacons to the bishops in the evangelical constitution, serving at tables, while the bishops waited on their ministry. The Levites killed the sacrifices, and then the priests needed only to sprinkle the blood and burn the fat: the Levites prepared the incense, the priests burnt it. They were to keep, not only Aaron's charge, but the charge of the whole congregation. Note, It is a great trust that is reposed in ministers, not only for the glory of Christ, but for the good of his church; so that they must not only keep the charge of the great high priest, but must also be faithful to the souls of men, in trust for whom a dispensation is committed to them. 2. the consideration upon which the Levites were demanded; they were taken instead of the first-born. The preservation of the first-born of Israel, when all the first-born of the Egyptians (with whom they were many of them mingled) were destroyed, was looked upon by him who never makes any unreasonable demands as cause sufficient of the appropriating of all the first-born thenceforward to himself (Num 3:13): All the first-born are mine. That was sufficient to make them his, though he had given no reason for it, for he is the sole fountain and Lord of all beings and powers; but because all obedience must flow from love, and acts of duty must be acts of gratitude, before they were challenged into peculiar services they were crowned with peculiar favours. Note, When he that made us saves us we are thereby laid under further obligations to serve him and live to him. God's right to us by redemption corroborates the right he has to us by creation. Now because the first-born of a family are generally the favourites, and some would think it a disparagement to have their eldest sons servants to the priests, and attending before the door of the tabernacle, God took the tribe of Levi entire for his own, in lieu of the first-born, Num 3:12. Note, God's institutions put no hardships upon men in any of their just interests or reasonable affections. It was presumed that the Israelites would rather part with the Levites than with the first-born, and therefore God graciously ordered the exchange; yet for us he spared not his own Son.

Tyndale Study Notes

On Numbers 3:1-3

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.
