The words of Moses in his wrath are broken. The Aaronic priesthood was of divine appointment; and thus in rejecting it, the conspirators were really rebelling against God.

For which cause, both thou and all thy company are gathered together against the Lord,.... For gathering together against his ministers, whom he had put into office to act under him, and endeavouring to overturn a constitution of his erecting, and resisting and not submitting to an ordinance of his, is interpreted gathering against him, and acting in opposition to him; see Romans 13:1,

and what is Aaron, that ye murmur against him? what is his transgression? what has he done? as Aben Ezra paraphrases it; he is not chargeable with any fault, he did not take upon him the office of high priest of himself, God called him to it, and put him in it; he is only his minister, and by no means to be blamed, and therefore it is unreasonable to envy him, or murmur against him; and, indeed, murmuring against him is murmuring against the Lord.

For which cause both thou and all thy company are gathered together against the LORD: and what is Aaron, that ye murmur against him?

16:11 Against the Lord - Whose chosen servant Aaron is. You strike at God through Aaron's sides.

16:1-11 Pride and ambition occasion a great deal of mischief both in churches and states. The rebels quarrel with the settlement of the priesthood upon Aaron and his family. Small reason they had to boast of the people's purity, or of God's favour, as the people had been so often and so lately polluted with sin, and were now under the marks of God's displeasure. They unjustly charge Moses and Aaron with taking honour to themselves; whereas they were called of God to it. See here, 1. What spirit levellers are of; those who resist the powers God has set over them. 2. What usage they have been serviceable. Moses sought instruction from God. The heart of the wise studies to answer, and asks counsel of God. Moses shows their privileges as Levites, and convicts them of the sin of undervaluing these privileges. It will help to keep us from envying those above us, duly to consider how many there are below us.
