Deuteronomy Chapter 18v1 – 8
“The Levitical priests, all the tribe of Levi, shall have no portion or inheritance with Israel. They shall eat the Lord‘s food offerings[a] as their inheritance. 2 They shall have no inheritance among their brothers; the Lord is their inheritance, as he promised them. 3 And this shall be the priests’ due from the people, from those offering a sacrifice, whether an ox or a sheep: they shall give to the priest the shoulder and the two cheeks and the stomach. 4 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 to stand and minister in the name of the Lord, him and his sons for all time.
6 “And if a Levite comes from any of your towns out of all Israel, where he lives—and he may come when he desires—to the place that the Lord will choose, 7 and ministers in the name of the Lord his God, like all his fellow Levites who stand to minister there before the Lord, 8 then he may have equal portions to eat, besides what he receives from the sale of his patrimony
