Numbers 16:41-47

But the very next morning the whole community of Israel began muttering again against Moses and Aaron, saying, “You have killed the LORD’s people!” As the community gathered to protest against Moses and Aaron, they turned toward the Tabernacle and saw that the cloud had covered it, and the glorious presence of the LORD appeared. Moses and Aaron came and stood in front of the Tabernacle, and the LORD said to Moses, “Get away from all these people so that I can instantly destroy them!” But Moses and Aaron fell face down on the ground. And Moses said to Aaron, “Quick, take an incense burner and place burning coals on it from the altar. Lay incense on it, and carry it out among the people to purify them and make them right with the LORD. The LORD’s anger is blazing against them—the plague has already begun.” Aaron did as Moses told him and ran out among the people. The plague had already begun to strike down the people, but Aaron burned the incense and purified the people.
