26 'And unto the Levites thou dost speak; and thou hast said unto them, When ye take from the sons of Israel the tithe which I have given to you from them, for your inheritance, then ye have lifted up from it the heave-offering of Jehovah, a tithe of the tithe; 27 and your heave-offering hath been reckoned to you as corn from the threshing-floor, and as fulness from the wine-vat; 28 so ye do lift up—ye also—the heave-offering of Jehovah from all your tithes which ye receive from the sons of Israel; and ye have given from it the heave-offering of Jehovah to Aaron the priest; 29 out of all your gifts ye do lift up the whole heave-offering of Jehovah; out of all its fat,—its hallowed part—out of it.
Matthew Henry's Commentary on Numbers 18:26-29
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.
