Numbers 18:21-28 As for the sons of Levi, behold, I give all the tithe in Israel as an allotment in exchange for their service in which they are serving, the service of the tent of appointment.

CLV⁽ⁱ⁾ ²¹ As for the sons of Levi, behold, I give all the tithe in Israel as an allotment in exchange for their service in which they are serving, the service of the tent of appointment. ²² The sons of Israel shall not come near again to the tent of appointment to bear sin so as to die. ²³ He, the Levite, will serve in the service of the tent of appointment, and they shall bear any depravity of theirs. It shall be an eonian statute throughout your generations so that in the midst of the sons of Israel they shall not be allotted an allotment, ²⁴ for it is the tithe of the sons of Israel which they shall raise up as a heave offering to Yahweh which I give to the Levites as an allotment. Therefore I say concerning them:No allotment in the midst of the sons of Israel shall they be allotted. ²⁵ Yahweh spoke to Moses, saying. ²⁶ As for the Levites, you shall speak and say to them:When you take from the sons of Israel the tithe which I give to you from them as your allotment, then you will raise up from it as a heave offering to Yahweh, a tenth of the tithe. ²⁷ Your heave offering will be reckoned to you like the grain from the threshing site and like the fullness from the wine vat. ²⁸ So shall you also raise up the heave offering of Yahweh from all your tithes which you take from the sons of Israel; and from it you will offer the heave offering of Yahweh to Aaron the priest.
