Numbers 18:19-21

¹⁹All the wave offerings of the holy things which the children of Israel offer to the LORD, I have given you and your sons and your daughters with you, as a portion forever. It is a covenant of salt forever before the LORD to you and to your offspring with you.”

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.
