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.
5-11. he spake unto Korah and unto all his company—They were first addressed, not only because they were a party headed by his own cousin and Moses might hope to have more influence in that quarter, but because they were stationed near the tabernacle; and especially because an expostulation was the more weighty coming from him who was a Levite himself, and who was excluded along with his family from the priesthood. But to bring the matter to an issue, he proposed a test which would afford a decisive evidence of the divine appointment.
Even to-morrow—literally, "in the morning," the usual time of meeting in the East for the settlement of public affairs.
the Lord will show who are his, … even him whom he hath chosen will he cause to come near unto him—that is, will bear attestation to his ministry by some visible or miraculous token of His approval.
