Numbers 16:1

Now Korah - took men - Had not these been the most brutish of men, could they have possibly so soon forgotten the signal displeasure of God manifested against them so lately for their rebellion. The word men is not in the original; and the verb ויקח vaiyikkach, and he took, is not in the plural but the singular, hence it cannot be applied to the act of all these chiefs. In every part of the Scripture where this rebellion is referred to it is attributed to Korah, (see Numbers 26:3, and Jde 1:11), therefore the verb here belongs to him, and the whole verse should be translated thus: - Now Korah, son of Yitsar son of Kohath, son of Levi, He Took even Dathan and Abiram, the sons of Eliab, and On, son of Peleth, Son Of Reuben; and they rose up, etc. This makes a very regular and consistent sense, and spares all the learned labor of Father Houbigant, who translates יקח yikkach, by rebellionem fecerunt, they rebelled, which scarcely any rule of criticism can ever justify. Instead of בני ראובן beney Reuben, Sons of Reuben, some MSS. have בן ben, Son, in the singular; this reading, supported by the Septuagint and the Samaritan text, I have followed in the above translation. But as Eliab and Peleth were both Reubenites, the common reading, Sons, may be safely followed.

Amram and Izhar were brothers (compare Exodus 6:18), and thus Korah, the "son," i. e. descendant of Izhar, was connected by distant cousinship with Moses and Aaron. Though being a Kohathite, he was of that division of the Levites which had the most honorable charge, yet as Elizaphan, who had been made "chief of the families of the Kohathites" Numbers 3:30, belonged to the youngest branch descended from Uzziel Numbers 3:27, Korah probably regarded himself as injured; and therefore took the lead in this rebellion. Of the others, On is not again mentioned. He probably withdrew from the conspiracy. Dathan, Abiram, and On were Reubenites; and were probably discontented because the birthright had been taken away from their ancestor Genesis 49:3, and with it the primacy of their own tribe among the tribes of Israel. The Reubenites encamped near to the Kohathites (compare Numbers 2:25 and plan), and thus the two families were conveniently situated for taking counsel together. One pretext of the insurrection probably was to assert the rights of primogeniture - on the part of the Reubenites against Moses, on the part of Korah against the appointment of Uzziel.

16:1 The son of Izhar - Amram's brother, 6:18 , therefore Moses and he were cousin germans. Moreover, Izhar was the second son of Kohath, whereas Elizaphan, whom Moses had preferred before him, and made prince or ruler of the Kohathites, Numbers 3:30 , was the son of Uzziel, the fourth son of Kohath. This, the Jewish writers say, made him malcontent, which at last broke forth into sedition. Sons of Reuben - These are drawn into confederacy with Korah, partly because they were his next neighbours, both being encamped on the south - side, partly in hopes to recover their rights of primogeniture, in which the priesthood was comprehended, which was given away from their father.
