Numbers 18
26 Ref `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;
27 Ref and your heave-offering hath been reckoned to you as corn from the threshing-floor, and as fulness from the wine-vat;
28 Ref so ye do lift up -- ye also -- the heave-offering of Jehovah from all your tithes which ye receive from the sons of Israel; and ye have given from it the heave-offering of Jehovah to Aaron the priest;
