Matthew Poole and continuators on Numbers 3:1

1 THese also are the generations of Aaron and Moses, in the day that the LORD spake with Moses in mount Sinai .

Which follow in this chapter.

(i. e.) Either 1. The things done by them, as the word generation is sometimes used, as Gen. 6. 9. and 25. 19. and 37. 2. Or rather 2. The Kindred or Family, for that is the subject of this chapter, and not their events or actions. Obj. Aarons Family indeed is here mentioned, but not Moses his Family. Answ. Moses his Family and Children are here included under the general name of the Amramite, ver. 27. which includes all the Children and Grand-chilfiren of Amram, the persons onely 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 Aarons posterity, whence Aaron is here put before Moses, who elsewhere is commonly named after him.

This seems to be added, because Nadab and Abihu mentioned ver. 2. were then alive, though dead at the time of taking this account.
