Numbers 16:43

40 To be a sign, kept in memory for ever by the children of Israel, that no man who is not of the seed of Aaron has the right of burning spices before the Lord, so that he may not be like Korah and his band: as the Lord said to him by the mouth of Moses.

41 But on the day after, all the children of Israel made an outcry against Moses and against Aaron, saying, You have put to death the Lord's people.

42 Now when the people had come together against Moses and Aaron, looking in the direction of the Tent of meeting, they saw the cloud covering it, and the glory of the Lord came before their eyes.

43 Then Moses and Aaron came to the front of the Tent of meeting.

44 And the Lord said to Moses,

45 Come out from among this people, so that I may send sudden destruction on them. And they went down on their faces.

46 And Moses said to Aaron, Take your vessel and put in it fire from the altar, and sweet spices, and take it quickly into the meeting of the people, and make them free from sin: for wrath has gone out from the Lord, and the disease is starting.
