46Moses said to Aaron, “Take your censer, place fire from the altar in it, and add incense. Go quickly to the congregation and make atonement for them, because wrath has come out from the LORD; the plague has begun.”
47So Aaron took the censer as Moses had ordered and ran into the midst of the assembly. And seeing that the plague had begun among the people, he offered the incense and made atonement for the people.
48He stood between the living and the dead, and the plague was halted.
49But those who died from the plague numbered 14, 700, in addition to those who had died on account of Korah.
50Then Aaron returned to Moses at the entrance to the Tent of Meeting, since the plague had been halted.
