III.

(1) These also are the generations of Aaron and Moses . . . --The name of Aaron is placed first, not only because he was the elder brother, but also because the ministry of Moses was restricted to his own person, and his sons are merely classed amongst the rest of the Levitical families in 1Chronicles 23:14; whereas the office of Aaron was perpetuated in the persons of his descendants. Hence we find no mention made in this place of the sons of Moses, but only of those of Aaron. The word generations here, as in the book of Genesis (e.g., Genesis 6:9; Genesis 25:19) and elsewhere, is used to denote the history; and in this sense the present and the following chapters pertain as much to Moses as to Aaron. Or the reference may be to the fact that Moses and Aaron were made the heads of the whole tribe of Levi, and therefore that the Levitical families generally are traced up equally to both.

Verse 1. - These... are the generations of Aaron and Moses. The word "generations" (toledoth) is used here in a peculiar and, so to speak, technical sense, with reference to what follows, as in Genesis 2:4; Genesis 6:9. It marks a new departure, looking down, not up, the course of history. Moses and Aaron were a beginning in themselves as the chosen heads of the chosen tribe: Moses having the higher office, but one entirely personal to himself; Aaron being the first of a long and eminent line of priests. The actual genealogy, therefore, is that of Aaron, and he is placed first. In the day. Apparently the day mentioned in Numbers 1:1; or it may be more general, as in Genesis 2:4.

3:1-13 There was much work belonging to the priests' office, and there were now only Aaron and his two sons to do it; God appoints the Levites to attend them. Those whom God finds work for, he will find help for. The Levites were taken instead of the first-born. When He that made us, saves us, as the first-born of Israel were saved, we are laid under further obligations to serve him faithfully. God's right to us by redemption, confirms the right he has to us by creation.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.
