Psalms 106:16

16. Envied Moses… and Aaron The allusion is to the conspiracy of Korah and his company. Numbers 16:0. Korah was a Levite, and Dathan and Abiram Reubenites. Psalms 106:1. These, with two hundred and fifty princes of various tribes, aspired to the high priesthood and leadership of the nation, demanding that these offices should be elective, and all be alike eligible to them. It is not certain whether the affair took place while at Kadesh the first time, or during the thirty-seven years of wandering. It was a fundamental rebellion against the whole organization of the nation by Jehovah, and punished as such.

Aaron the saint of the Lord Or, holy one of Jehovah. This was the point at issue, whether Aaron and Moses were the sanctified ones for their offices, exclusive of the common people.
