Numbers 16:44

41 But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, Ye have killed the people of the LORD.

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

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

44 And the LORD spoke to Moses, saying,

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

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

47 And Aaron took as Moses commanded, and ran into the midst of the congregation; and behold, the plague was begun among the people: and he put on incense, and made an atonement for the people.
