Deuteronomy 18:3-5

Complete Jewish Bible

³ “The cohanim will have the right to receive from the people, from those offering a sacrifice, whether ox or sheep, the shoulder, the jowls and the stomach. ⁴ You will also give him the firstfruits of your grain, new wine and olive oil, and the first of the fleece of your sheep. ⁵ For Adonai your God has chosen him from all your tribes to stand and serve in the name of Adonai, him and his sons forever.
