Deuteronomy 18:3-5

Amplified Bible, Classic Edition

³ And this shall be the priest’s due from the people, from those who offer a sacrifice, whether it be ox or sheep: they shall give to the priest the shoulder and the two cheeks and the stomach.

⁴ The firstfruits of your grain, of your new wine, and of your oil, and the first or best of the fleece of your sheep you shall give the priest.

⁵ For the Lord your God has chosen him out of all your tribes to stand to minister in the name [and presence] of the Lord, him and his sons forever.
