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.
