22 Neither shall the children of Israel henceforth come near the tent of meeting, to bear sin and die. 23 But the Levite, he shall perform the service of the tent of meeting, and they shall bear their iniquity: it is an everlasting statute throughout your generations. And among the children of Israel shall they possess no inheritance; 24 for I have given for an inheritance to the Levites the tithes of the children of Israel, which they offer as a heave-offering to Jehovah; therefore I have said of them, They shall possess no inheritance among the children of Israel.
Matthew Henry's Commentary on Numbers 18:22-24
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.
