Numbers 16:16-21

16Moses said to Korah, “You and all your followers are to appear before the Lord tomorrow—you and they and Aaron. 17Each man is to take his censer and put incense in it—250 censers in all—and present it before the Lord. You and Aaron are to present your censers also.” 18So each of them took his censer, put burning coals and incense in it, and stood with Moses and Aaron at the entrance to the tent of meeting. 19When Korah had gathered all his followers in opposition to them at the entrance to the tent of meeting, the glory of the Lord appeared to the entire assembly. 20The Lord said to Moses and Aaron, 21“Separate yourselves from this assembly so I can put an end to them at once.”
