Numbers 16:17-19

New International Version - UK

¹⁷ Each 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.’ ¹⁸ So 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. ¹⁹ When 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.
