Deuteronomy 18:3-5

English Standard Version

³ And this shall be the priests' due from the people, from those offering a sacrifice, whether an ox or a sheep: ^(A)they shall give to the priest the shoulder and the two cheeks and the stomach. ^4 (B)The firstfruits of your grain, of your wine and of your oil, and the first fleece of your sheep, you shall give him. ⁵ For the Lord your God has chosen him out of all your tribes ^(C)to stand and minister in the name of the Lord, him and his sons for all time.
