9 The sons of Eliab: Nemuel, and Dathan, and Abiram. These are that Dathan and Abiram, who were called of the congregation, who strove against Moses and against Aaron in the company of Korah, when they strove against Yahweh, 10 and the earth opened its mouth, and swallowed them up together with Korah, when that company died; what time the fire devoured two hundred fifty men, and they became a sign. 11 Notwithstanding, the sons of Korah didn’t die.
Matthew Henry's Commentary on Numbers 26:9-11
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.
