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, 15 every one opening a womb of all flesh which they bring near to Jehovah, among man and among beast, is thine; only, thou dost certainly ransom the first-born of man, and the firstling of the unclean beast thou dost ransom. 16 'And their ransomed ones from a son of a month, thou dost ransom with thy valuation, of silver, five shekels, by the shekel of the sanctuary, twenty gerahs it 'is'. 17 'Only, the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou dost not ransom, holy they 'are': their blood thou dost sprinkle on the altar, and of their fat thou makest perfume, a fire-offering of sweet fragrance to Jehovah, 18 and their flesh is thine, as the breast of the wave-offering, and as the right leg, it is thine; 19 all the heave-offerings of the holy things which the sons of Israel lift up to Jehovah I have given to thee and to thy sons, and to thy daughters with thee, by a statute age-during, a covenant of salt, age-during it 'is' before Jehovah, to thee and to thy seed with thee.'
20 And Jehovah saith unto Aaron, 'In their land thou dost not inherit, and a portion thou hast not in their midst: I 'am' thy portion, and thine inheritance in the midst of the sons of Israel;

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.

(Read Numbers 18:20-32)
As Israel was a people not to be numbered among the nations, so Levi was a tribe to be distinguished from the rest. Those who have God for their Inheritance and their Portion for ever, ought to look with holy contempt and indifference upon the possessions of this world. The Levites were to give God his dues out of their tithes, as well as the Israelites out of their increase. See, in 2 Thessalonians 3:10. 2. We must be sure that God has his dues out of it. We have the comfort of our substance, when we have honoured the Lord with it. Ye shall bear no sin by reason of it, when ye have heaved the best from it. We should give alms of such things as we have, that all may be holy and comfortable to us.
