Numbers 16:1-3

1Now Korah the son of Izhar, the son of Kohath, the son of Levi, with Dathan and Abiram the sons of Eliab, and On the son of Peleth, sons of Reuben, took men;

2and they rose up before Moses with some of the children of Israel, two hundred and fifty leaders of the congregation, representatives of the congregation, men of renown.

3They gathered together against Moses and Aaron, and said to them, “You take too much upon yourselves, for all the congregation is holy, every one of them, and the Lord is among them. Why then do you exalt yourselves above the assembly of the Lord?”
