Numbers 16:17-19

American Standard Version

¹⁷ and take ye every man his censer, and put incense upon them, and bring ye before Jehovah every man his censer, two hundred and fifty censers; thou also, and Aaron, each his censer. ¹⁸ And 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. ¹⁹ And Korah assembled all the congregation against them unto the door of the tent of meeting: and the glory of Jehovah appeared unto all the congregation.
