11 This also is yours, the offering of their gift, all the wave offerings of the people of Israel; I have given them to you, and to your sons and daughters with you, as a perpetual due; every one who is clean in your house may eat of it.

Matthew Henry's Commentary on Numbers 18:11

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.
