Numbers 18:26–28

“Moreover, you shall speak and say to the Levites, ‘When you take from the people of Israel the tithe that I have given you from them for your inheritance, then you shall present a contribution from it to the Lord, a tithe of the tithe. And your contribution shall be counted to you as though it were the grain of the threshing floor, and as the fullness of the winepress. So you shall also present a contribution to the Lord from all your tithes, which you receive from the people of Israel. And from it you shall give the Lord’s contribution to Aaron the priest.

“Speak to the Levites and say to them: ‘When you receive from the Israelites the tithe I give you as your inheritance, you must present a tenth of that tithe as the Lord’s offering. Your offering will be reckoned to you as grain from the threshing floor or juice from the winepress. In this way you also will present an offering to the Lord from all the tithes you receive from the Israelites. From these tithes you must give the Lord’s portion to Aaron the priest.

“Speak to the Levites and tell them: When you receive from the Israelites the tenth that I have given you as your inheritance, you are to present part of it as an offering to the Lord—a tenth of the tenth. Your offering will be credited to you as if it were your grain from the threshing floor or the full harvest from the winepress. You are to present an offering to the Lord from every tenth you receive from the Israelites. Give some of it to the priest Aaron as an offering to the Lord.

“Give these instructions to the Levites: When you receive from the people of Israel the tithes I have assigned as your allotment, give a tenth of the tithes you receive—a tithe of the tithe—to the Lord as a sacred offering. The Lord will consider this offering to be your harvest offering, as though it were the first grain from your own threshing floor or wine from your own winepress. You must present one-tenth of the tithe received from the Israelites as a sacred offering to the Lord. This is the Lord’s sacred portion, and you must present it to Aaron the priest.

“You will speak to the Levites and say to them, ‘When you receive the tithe from the Israelites that I have given to you from them for your inheritance, you will present a contribution from it to Yahweh, a tithe from a tithe. Your contribution will be credited to you like the grain from the threshing floor and like the produce from the press. So you will present your own contribution to Yahweh from all your tithes that you receive from the Israelites; from it you will give the contribution of Yahweh to Aaron the priest.

Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the Lord, even a tenth part of the tithe. And this your heave offering shall be reckoned unto you, as though it were the corn of the threshingfloor, and as the fulness of the winepress. Thus ye also shall offer an heave offering unto the Lord of all your tithes, which ye receive of the children of Israel; and ye shall give thereof the Lord’s heave offering to Aaron the priest.
