Commentary on Numbers 26:11

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Numbers 26:5-51: This is the register of the tribes as they were now enrolled, in the same order that they were numbered in ch. 1. Observe, I. The account that is here kept of the families of each tribe, which must not be understood of such as we call families, those that live in a house together, but such as were the descendants of the several sons...
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Numbers 26:11: The children of Gad, after their families tribe was numbered next to Simeon,.... because it lay encamped with that under the standard of Reuben. There is a little variation in the names of two or three of his sons, from those by which they are called Gen 46:16, instead of Ziphion, here Zephon; and for Haggai, here Haggi; and what is much wider, for Ezbon, here Ozni.
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Numbers 26:11: Notwithstanding the children of Korah died not--Either they were not parties to their father's crime, or they withdrew from it by timely repentance. His descendants became famous in the time of David, and are often mentioned in the Psalms [Psa 42:1; Psa 44:1; Psa 45:1; Psa 46:1; Psa 47:1; Psa 48:1; Psa 49:1; Psa 84:1; Psa 85:1; Psa 87:1; Psa 88:1], also in Ch1 6:22, Ch1 6:38.
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Numbers 26:5-11: 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.
