Deuteronomy 18:3-5

New Catholic Bible

³ This is the portion due to the priest from the people who offer a sacrifice of either an ox or a sheep: the shoulder, the jowl, and the inner organs. ⁴ You will give them the firstfruits of the grain, the wine, and the oil, as well as the first sheering of the sheep ⁵ for the Lord, your God, has chosen him and his sons out of all of the tribes to minister in the Lord’s name forever.
