Numbers 18:19-21

Amplified Bible

¹⁹ All the offerings of the holy things, which the Israelites offer to the Lord I have given to you and to your sons and your daughters with you as a continual allotment. It is an everlasting covenant of ^[a]salt [that cannot be dissolved or violated] before the Lord to you and to your descendants with you.” ²⁰ Then the Lord said to Aaron, “You shall have no inheritance in the land [of the Israelites], nor have any portion [of land] among them. I am your portion and your inheritance among the children of Israel.

²¹ “Behold, I have given the Levites all the tithe in Israel as an inheritance, in return for their service which they perform, the service of the Tent of Meeting (tabernacle).
