Numbers 18:24-27

²⁴but the tithe of the sons of Israel which they lift up to Jehovah, a heave-offering, I have given to the Levites for inheritance; therefore I have said of them, In the midst of the sons of Israel they have no inheritance.'

²⁵And Jehovah speaketh unto Moses, saying,

²⁶'And unto the Levites thou dost speak; and thou hast said unto them, When ye take from the sons of Israel the tithe which I have given to you from them, for your inheritance, then ye have lifted up from it the heave-offering of Jehovah, a tithe of the tithe;

²⁷and your heave-offering hath been reckoned to you as corn from the threshing-floor, and as fulness from the wine-vat;
