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 their 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.
the Levites . . . offer . . . a tenth of the tithe--Out of their own they were to pay tithes to the priests equally as the people gave to them. The best of their tithes was to be assigned to the priests, and afterwards they enjoyed the same liberty to make use of the remainder that other Israelites had of the produce of their threshing-floors and wine-presses.
Ye shall offer up an heave - offering - They who are employed in assisting the devotions of others, must be sure to pay their own as an heave - offering. Prayers and praises, or rather the heart lifted up in them, are now our heave - offerings.
