Numbers 16:46-48

46And Moses said unto Aaron, Take thy censer, and put fire therein from off the altar, and lay incense thereon, and carry it quickly unto the congregation, and make atonement for them: for there is wrath gone out from Jehovah; the plague is begun. 47And Aaron took as Moses spake, and ran into the midst of the assembly; and, behold, the plague was begun among the people: and he put on the incense, and made atonement for the people. 48And he stood between the dead and the living; and the plague was stayed.
