8 And Jehovah speaketh unto Aaron: 'And I, lo, I have given to thee the charge of My heave-offerings, of all the hallowed things of the sons of Israel—to thee I have given them for the anointing, and to thy sons, by a statute age-during. 9 This is thine of the most holy things, from the fire: all their offering, to all their present, and to all their sin-offering, and to all their guilt-offering, which they give back to Me, is most holy to thee, and to thy sons; 10 in the holy of holies thou dost eat it; every male doth eat it; holy it is to thee. 11 'And this 'is' thine: the heave-offering of their gift, to all the wave-offerings of the sons of Israel, to thee I have given them, and to thy sons, and to thy daughters with thee, by a statute age-during; every clean one in thy house doth eat it; 12 all the best of the oil, and all the best of the new wine, and wheat—their first-'fruits' which they give to Jehovah—to thee I have given them. 13 'The first-fruits of all that 'is' in their land, which they bring in to Jehovah, are thine; every clean one in thy house doth eat it; 14 every devoted thing in Israel is thine,

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.
