Numbers 18:20-32

20Then the Lord said to Aaron, “1You shall have no inheritance in their land nor own any portion among them; 2I am your portion and your inheritance among the sons of Israel.

21“To the sons of Levi, behold, I have given all the 3tithe in Israel for an inheritance, in return for their service which they perform, the service of the tent of meeting. 224The sons of Israel shall not come near the tent of meeting again, or they will bear sin and die. 23Only the Levites shall perform the service of the tent of meeting, and they shall 5bear their iniquity; it shall be a perpetual statute throughout your generations, and among the sons of Israel 6they shall have no inheritance. 24For the tithe of the sons of Israel, which they offer as an offering to the Lord, I have given to the Levites for an inheritance; therefore I have said concerning them, ‘7They shall have no inheritance among the sons of Israel.’”

25Then the Lord spoke to Moses, saying, 26“Moreover, you shall speak to the Levites and say to them, ‘When you take from the sons of Israel 8the tithe which I have given you from them for your inheritance, then you shall present an offering from it to the Lord, a 9tithe of the tithe. 27Your offering shall be reckoned to you as the grain from the threshing floor or the full produce from the wine vat. 28So you shall also present an offering to the Lord from your tithes, which you receive from the sons of Israel; and from it you shall give the Lord’s offering to Aaron the priest. 29Out of all your gifts you shall present every offering due to the Lord, from all the 10best of them, 11the sacred part from them.’ 30You shall say to them, ‘When you have 12offered from it the best of it, then the rest shall be reckoned to the Levites as the product of the threshing floor, and as the product of the wine vat. 31You may eat it anywhere, you and your households, for it is your compensation in return for your service in the tent of meeting. 32You will bear no sin by reason of it when you have 13offered the 14best of it. But you shall not 15profane the sacred gifts of the sons of Israel, or you will die.’”
