Numbers 16:44

And it came to pass, when the congregation was gathered against Moses and against Aaron, that they looked toward the tabernacle of the congregation: and, behold, the cloud covered it, and the glory of the LORD appeared.

And Moses and Aaron came before the tabernacle of the congregation.

Get you up from among this congregation, that I may consume them as in a moment. And they fell upon their faces.

And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the LORD; the plague is begun.
