Deuteronomy 18:1-3

Darby Translation

18 The priests, the Levites, [and] the whole tribe of Levi, shall have no portion nor inheritance with Israel: Jehovah's offerings by fire, and his inheritance shall they eat,

² but they shall have no inheritance among their brethren: Jehovah, he is their inheritance, as he hath said unto them.

³ And this shall be the priest's due from the people, from them that sacrifice a sacrifice, whether ox, or sheep: they shall give unto the priest the shoulder, and the jawbones, and the maw.
