Numbers 16:47-48

⁴⁷And when Aaron had done this, and had run to the midst of the multitude, which the burning wasted then, he offered incense; (And Aaron did this, and ran to the midst of the multitude, who were already dying from the plague, and he offered the incense;)

⁴⁸and he stood betwixt the dead men and the living, and he prayed for the people, and the vengeance ceased. (and he stood there among the living and the dead, and made amends for the people, and then the plague ceased.)
