Numbers 18:20-24

²⁰The LORD said to Aaron, “You shall have no inheritance in their land, neither shall you have any portion amongst them. I am your portion and your inheritance amongst the children of Israel.

²¹“To the children of Levi, behold, I have given all the tithe in Israel for an inheritance, in return for their service which they serve, even the service of the Tent of Meeting.

²²Henceforth the children of Israel shall not come near the Tent of Meeting, lest they bear sin, and die.

²³But the Levites shall do the service of the Tent of Meeting, and they shall bear their iniquity. It shall be a statute forever throughout your generations. Amongst the children of Israel, they shall have no inheritance.

²⁴For the tithe of the children of Israel, which they offer as a wave offering to the LORD, I have given to the Levites for an inheritance. Therefore I have said to them, ‘Amongst the children of Israel they shall have no inheritance.’”
