20 And the Lord said to Aaron, "You shall have no inheritance in their land, neither shall you have any portion among them; I am your portion and your inheritance among the people of Israel. 21 "To the Levites I have given every tithe in Israel for an inheritance, in return for their service which they serve, their service in the tent of meeting. 22 And henceforth the people of Israel shall not come near the tent of meeting, lest they bear sin and die. 23 But the Levites shall do the service of the tent of meeting, and they shall bear their iniquity; it shall be a perpetual statute throughout your generations; and among the people of Israel they shall have no inheritance. 24 For the tithe of the people of Israel, which they present as an offering to the Lord, I have given to the Levites for an inheritance; therefore I have said of them that they shall have no inheritance among the people of Israel."

Commentary on Numbers 18:20-32
(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.
