John Calvin Commentary Numbers 16:3

"and they assembled themselves together against Moses and against Aaron, and said unto them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and Jehovah is among them: wherefore then lift ye up yourselves above the assembly of Jehovah?" — Numbers 16:3 (ASV)

You take too much upon you.⁸⁹ Some explain this phrase as meaning, “Let it be enough,” as if they desired to put an end to the tyranny of Moses. However, I am rather of the opinion that by it they meant to lodge a charge of presumptuous and sacrilegious supremacy, as if Moses and Aaron had not only usurped more than their right, but had also robbed God of His supreme authority. They, therefore, reproach the holy men with having impiously subjected to themselves the inheritance of God.

Thus we see that God’s faithful servants, whatever their moderation may be, are still not exempt from false accusations. Moses was an extraordinary example, not only of integrity but also of humility and gentleness; yet he is called proud and violent, as if he unworthily oppressed the people of God.

Observe further, that God permits His servants to be loaded with such unjust slanders to teach them that they must expect their reward elsewhere than from the world; and that He may humble them and test their endurance. Let us learn, then, to harden ourselves, so as to be prepared, though we do well, to be spoken evil of.

These ungodly and seditious men betray their senselessness as well as their impudence. For by what right do they seek to degrade Moses and Aaron? Because, indeed, God dwells among the people, and all in the congregation are holy! But holiness is neither destructive of subordination, nor does it introduce confusion, nor does it release believers from the obligation to obey the laws.

It is madness in them, then, to infer that those whom God has sanctified are not subject to the yoke; yet they maliciously stigmatize as tyranny that care of the people which God has entrusted to His servants, as if they would purposely turn light into darkness.

⁸⁹ “Sat sit vobis;” let it be enough for you. — Lat.
