8 God spoke to Aaron, "I am personally putting you in charge of my contributions, all the holy gifts I get from the People of Israel. I am turning them over to you and your children for your personal use. This is the standing rule.

Matthew Henry's Commentary on Numbers 18:8

Commentary on Numbers 18:8-19

(Read Numbers 18:8-19)

All believers are spiritual priests, and God has promised to take care of them. Godliness has the promise of the life that now is. And from the provision here made for the priests, the apostle shows that it is the duty of christian churches to maintain their ministers. Scandalous maintenance makes scandalous ministers. The priests were to be wholly devoted to their ministry, not diverted from it, or disturbed in it, by worldly care or business. Also, that they might be examples of living by faith, not only in God's providence, but in his ordinances. The best should be offered for the first-fruits unto the Lord. Those who think to save, by putting God off with the refuse, deceive themselves, for God is not mocked.
