Numbers 16:43-47

Then Moses and Aaron came to the front of the tent of meeting,

and the Lord spoke to Moses, saying,

“Get away from among this congregation so that I may consume them instantly.” Then they fell on their faces.

And Moses said to Aaron, “Take your censer and put fire in it from the altar, and place incense on it; then bring it quickly to the congregation and make atonement for them, for wrath has gone out from the Lord, the plague has begun!”

Then Aaron took it just as Moses had spoken, and he ran into the midst of the assembly; and behold, the plague had begun among the people. So he put on the incense and made atonement for the people.
