Numbers 16:44-50

44and the Lord said to Moses,

45“Get away from all these people so that I can instantly destroy them!” But Moses and Aaron fell face down on the ground.

46And 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.”

47Aaron 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.

48He stood between the dead and the living, and the plague stopped.

49But 14,700 people died in that plague, in addition to those who had died in the affair involving Korah.

50Then because the plague had stopped, Aaron returned to Moses at the entrance of the Tabernacle.
