Numbers 18:19-21 Modern English Version (MEV)
19 All the offerings of the holy things which the children of Israel offer to the Lord I have given to you, and to your sons and your daughters with you, as an eternal statute. It is a covenant of salt forever before the Lord, to you and to your seed with you.
20 The Lord said to Aaron: You will not have an inheritance in their land, nor will you have any territory among them. I am your territory and your inheritance among the children of Israel.
Tithes for Supporting the Levites
21 I have given the children of Levi all the tithes in Israel for an inheritance, for their service, which they serve, even the service of the tent of meeting.
