Deuteronomy 18:1-5

“Remember that the Levitical priests—that is, the whole of the tribe of Levi—will receive no allotment of land among the other tribes in Israel. Instead, the priests and Levites will eat from the special gifts given to the LORD, for that is their share. They will have no land of their own among the Israelites. The LORD himself is their special possession, just as he promised them. “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.
