Deuteronomy 18:2-4

American Standard Version

² And they shall have no inheritance among their brethren: Jehovah is their inheritance, as he hath spoken unto them. ³ And this shall be the priests’ due from the people, from them that offer a sacrifice, whether it be ox or sheep, that they shall give unto the priest the shoulder, and the two cheeks, and the maw. ⁴ The first-fruits of thy grain, of thy new wine, and of thine oil, and the first of the fleece of thy sheep, shalt thou give him.
