NUMBERS 16:16-19

¹⁶And Moses said unto Korah, Be thou and all thy congregation before the LORD, thou, and they, and Aaron, tomorrow:

¹⁷and take ye every man his censer, and put incense upon them, and bring ye before the LORD every man his censer, two hundred and fifty censers; thou also, and Aaron, each his censer.

¹⁸And they took every man his censer, and put fire in them, and laid incense thereon, and stood at the door of the tent of meeting with Moses and Aaron.

¹⁹And Korah assembled all the congregation against them unto the door of the tent of meeting: and the glory of the LORD appeared unto all the congregation.
