Psalms 106:16

They envied Moses also in the camp,.... That he should be generalissimo there, have the sole command of the people, and be their leader and chief magistrate. Gifts qualifying men for civil government are from the Lord, and these commonly draw the envy of others upon them; who, though they pretend patriotism and the good of their country, yet seek themselves; and would be in the places of those they envy and speak against; which was the case of Dathan and Abiram, the sons of Reuben, who thought themselves as fit, and had a better right, as being the sons of Jacob's firstborn, to command, than Moses.

And Aaron the saint of the Lord; who was not only a holy good man, but was separated from his brethren, sanctified, and put into the priest's office, and this drew upon him the envy of many of the Levites, at the head of whom was Korah, a Levite; these envied that he should be the high priest, and that this office should be restrained to his family; now the envy to each of these is ascribed to the whole body of the people, though discovered only in some, because it was not opposed by them; see Numbers 16:1.
