Numbers 16:48 KJV

46And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the LORD; the plague is begun.

47And Aaron took as Moses commanded, and ran into the midst of the congregation; and, behold, the plague was begun among the people: and he put on incense, and made an atonement for the people.

48And he stood between the dead and the living; and the plague was stayed.

49Now they that died in the plague were fourteen thousand and seven hundred, beside them that died about the matter of Korah.

50And Aaron returned unto Moses unto the door of the tabernacle of the congregation: and the plague was stayed.
