21 "I'm giving the Levites all the tithes of Israel as their pay for the work they do in the Tent of Meeting. 22 Starting now, the rest of the People of Israel cannot wander in and out of the Tent of Meeting; they'll be penalized for their sin and the penalty is death. 23 It's the Levites and only the Levites who are to work in the Tent of Meeting and they are responsible for anything that goes wrong. This is the regular rule for all time. They get no inheritance among the People of Israel; 24 instead I turn over to them the tithes that the People of Israel present as an offering to God. That's why I give the ruling: They are to receive no land-inheritance among the People of Israel."
Matthew Henry's Commentary on Numbers 18:21-24
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.
