And Aaron took as Moses commanded, and ran into the midst of the congregation; and, behold, the plague had begun among the people: and he put on incense, and made an atonement for the people.
All Commentaries on Numbers 16:47 Go To Numbers 16
Ambrose of Milan
AD 397
Clearly the man [Aaron], who is proposed as a leader to all, is worthy. For when fateful death crept into the midst of the people because of the insolent, he threw himself between the “living and the dead” to restrain death, lest many should perish. Truly the man is priestly in mind and heart who throws himself with pious love before the flock of the Lord like a good shepherd. In this way he broke the sting of death. He held off the attack; he put an end to the dying. Piety assisted merit, since he offered himself for those who resisted.
