Numbers 18:20-23

20The Lord said to Aaron, “You will have no land or property of your own as the other Israelites will have. I am your possession and your property among the Israelites.

21“I am giving the Levites one-tenth of every Israelite’s income. This is in return for the work they do at the tent of meeting.

22The other Israelites must never again come near the tent of meeting. Otherwise, they’ll suffer the consequences of their sin and die.

23Only the Levites will do the work at the tent of meeting. They will be responsible for their own sins. This is a permanent law for future generations. They will own no property as the other Israelites will.
