Numbers 18:30-32

Young's Literal Translation

³⁰ `And thou hast said unto them, In your lifting up its fat out of it, then it hath been reckoned to the Levites, as increase of a threshing-floor, and as increase of a wine-vat;

³¹ and ye have eaten it in every place, ye and your households, for it [is] your hire in exchange for your service in the tent of meeting;

³² and ye bear no sin for it, in your lifting up its fat out of it, and the holy things of the sons of Israel ye do not pollute, and ye die not.'
