Deuteronomy 18:3-9

“These are the parts the priests may claim as their share from the cattle, sheep, and goats that the people bring as offerings: the shoulder, the cheeks, and the stomach. You must also give to the priests the first share of the grain, the new wine, the olive oil, and the wool at shearing time. For the LORD your God chose the tribe of Levi out of all your tribes to minister in the LORD’s name forever. “Suppose a Levite chooses to move from his town in Israel, wherever he is living, to the place the LORD chooses for worship. He may minister there in the name of the LORD his God, just like all his fellow Levites who are serving the LORD there. He may eat his share of the sacrifices and offerings, even if he also receives support from his family. “When you enter the land the LORD your God is giving you, be very careful not to imitate the detestable customs of the nations living there.
