And Aaron took as Moses commanded and ran into the midst of the congregation; and behold, the plague was begun among the people: and he put on incense and made an atonement for the people. And he stood between the dead and the living; and the plague was stayed. – Numbers 16:47-48
The authority of Moses and Aaron had been disputed by an ambitious man belonging to an elder branch of the family of Levi, who had craftily joined with himself certain factious spirits of the tribe of Reuben, who themselves also sought to attain to power by their supposed rights through Reuben the first born. By a singular judgment from heaven, God had proved that rebellion against Moses was a mortal sin. He had bidden the earth open its mouth and swallow up all the traitors, and both Levites and Reubenites had disappeared, covered in a living grave. One would have imagined that from this time the murmurings of the children of Israel would have ceased…Yet…(on) the very morrow after that solemn transaction, the whole of the people of Israel gathered themselves together, and with unholy clamors surrounded Moses and Aaron, charging them with having put to death the people of the Lord.
Aaron deserves to be very highly praised for his patriotic affection for a people who were the most rebellious and stiff-necked that ever grieved the heart of a good man. You must remember that in this case he was the aggrieved party. The clamor was made against Moses and against Aaron, yet it was Moses and Aaron who interceded and saved the people. They were the offended ones yet were they the saving ones. You know who it is to whom we give that name of “Lover of my soul.” You will be able to see in Aaron the lover of Israel, in Jesus the lover of His people. ~ C.H. Spurgeon
