Numbers 16:18, 46

So each of them took his censer, put burning coals and incense in it, and stood with Moses and Aaron at the entrance to the tent of meeting.

Then Moses said to Aaron, “Take your censer and put incense in it, along with burning coals from the altar, and hurry to the assembly to make atonement for them. Wrath has come out from the LORD; the plague has started.”
