Num 26:5-11
The families of Reuben tally with Gen 46:9; Exo 6:14, and 1Ch 5:3. The plural בּני (sons), in Num 26:8, where only one son is mentioned, is to be explained from the fact, that several sons of this particular son (i.e., grandsons) are mentioned afterwards. On Dathan and Abiram, see at Num 16:1 and Num 16:32. See also the remark made here in Num 26:10 and Num 26:11, viz., that those who were destroyed with the company of Korah were for a sign (נס, here a warning); but that the sons of Korah were not destroyed along with their father.
