Bamidbar 26:9 Meaning and Commentary

Numbers 26:9

And the sons of Eliab; Nemuel, and Dathan, and Abiram
Of Nemuel we nowhere else read either he died without children, or he and his family perished with his brethren, being concerned with them in the conspiracy; or the family of the Palluite was in his line; one of the same name may be observed in the tribe of Simeon:

this is that Dathan and Abiram, which were famous in the congregation;
either before their rebellion, for their power and authority, being heads of their fathers' houses; or for their parts and abilities, being men of great wisdom and sense; or for their zeal, activity, and usefulness; or after it, and became famous, or rather infamous, on account of it, see ( Numbers 16:2 )

who strove against Moses and against Aaron in the company of Korah,
when they strove against the Lord;
who joined with Korah and his company, and quarrelled with Moses and Aaron about the priesthood; with Moses for putting Aaron into it, and with Aaron for accepting it, and officiating in it; and so with the Lord himself, by whose orders he was invested with it.
