Commentary

Thus speak unto the Levites, and say unto them,.... Aaron was to tell them what a provision would be made for them on account of the ir service, but Moses was to inform them what part Aaron was to have out of it: when ye take of the children of Israel the tithes which I have given you from them for your inheritance; which was done at the time of their harvest, and of the ingathering of the fruits of the earth: then ye shall offer up an heave offering of it for the Lord; in token of gratitude for the liberal provision he had made for the maintenance of them: even a tenth part of the tithe; a tenth part out of the tenth of the produce of the land of Israel.
