Deuteronomy 18:1-5

“The Levitical priests, the entire tribe of Levi, shall own [privately] no portion [of land] or inheritance with Israel; they shall eat the LORD’S offerings by fire and His portion. They shall have no inheritance [of land] among their countrymen (brothers, brethren); the LORD is their inheritance, as He promised them. “Now this shall be the priests’ portion from the people, from those offering a sacrifice, either an ox or a sheep: they shall give to the priest the shoulder and the two cheeks and the stomach. You shall also give him the first fruits of your grain, your new wine [the first of the season], and your [olive] oil, and the first sheared fleece of your sheep. For the LORD your God has chosen him, him and his sons from all your tribes, to stand and serve in the name of the LORD forever.
