Numbers 16:46-48

Young's Literal Translation

⁴⁶ and Moses saith unto Aaron, `Take the censer, and put on it fire from off the altar, and place perfume, and go, hasten unto the company, and make atonement for them, for the wrath hath gone out from the presence of Jehovah -- the plague hath begun.'

⁴⁷ And Aaron taketh as Moses hath spoken, and runneth unto the midst of the assembly, and lo, the plague hath begun among the people; and he giveth the perfume, and maketh atonement for the people,

⁴⁸ and standeth between the dead and the living, and the plague is restrained;
