3:1 These also [are] the {a} generations of Aaron and Moses in the day [that] the LORD spake with Moses in mount Sinai.
(a) Or, families and kindreds.
3:1 These - Which follow in this chapter . The generations - The kindred or family. Moses his family and children are here included under the general name of the Amramites, Nu 3:27, which includes all the children and grand - children of Amram, the persons only of Aaron and Moses being excepted. And the generations of Moses are thus obscurely mentioned, because they were but common Levites, the priesthood being given solely to Aaron's posterity, whence Aaron is here put before Moses, who elsewhere is commonly named after him. In Sinai - Nadab and Abihu, were then alive, though dead at the time of taking this account.
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.
