9 And the sons of Eliab: Nemuel and Dathan and Abiram. These are the same Dathan and Abiram who had a place in the meeting of the people, who together with Korah made an outcry against Moses and Aaron and against the Lord: 10 And they went down into the open mouth of the earth, together with Korah, when death overtook him and all his band; at the time when two hundred and fifty men were burned in the fire, and they became a sign. 11 But death did not overtake the sons of Korah.

Commentary on Numbers 26:1-51
(Read Numbers 26:1-51)
Moses did not number the people but when God commanded him. We have here the families registered, as well as the tribes. The total was nearly the same as when numbered at mount Sinai. Notice is here taken of the children of Korah; they died not, as the children of Dathan and Abiram; they seem not to have joined even their own father in rebellion. If we partake not of the sins of sinners, we shall not partake of their plagues.
