Bible Verses About Aaron: Stays the plague by priestly intercession

Moshe said to Aharon, "Take your fire pan, put fire from the altar in it, lay incense on it, and hurry with it to the assembly to make atonement for them, because anger has gone out from ADONAI, and the plague has already begun!"

Aharon took it, as Moshe had said, and ran into the middle of the assembly. There the plague had already begun among the people, but he added the incense and made atonement for the people.

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