Numbers 16:2-3

2and they stood before Moses, 1together with some of the sons of Israel, 250 leaders of the congregation 23chosen in the assembly, men of renown. 3They assembled together 4against Moses and Aaron, and said to them, “56You have gone far enough! For all the congregation are holy, every one of them, and 7the Lord is in their midst; so why do you exalt yourselves above the assembly of the Lord?”
