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.

²⁰  And Jehovah spake unto Moses and unto Aaron, saying,

²¹  Separate yourselves from among this congregation, that I may consume them in a moment.
