Numbers 16:42-48

42But when the assembly gathered in opposition to Moses and Aaron and turned toward the tent of meeting, suddenly the cloud covered it and the glory of the LORD appeared. 43Then Moses and Aaron went to the front of the tent of meeting, 44and the LORD said to Moses,

45“Get away from this assembly so I can put an end to them at once.” And they fell facedown. 46Then 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.” 47So Aaron did as Moses said, and ran into the midst of the assembly. The plague had already started among the people, but Aaron offered the incense and made atonement for them. 48He stood between the living and the dead, and the plague stopped.
