Numbers 18:20-27

²⁰Yahweh said to Aaron, “You will have no inheritance in the people's land, nor will you have any share of property among the people. I am your share and inheritance among the people of Israel.

²¹To the descendants of Levi, look, I have given all the tithes in Israel as their inheritance in return for the service that they provide in working at the tent of meeting.

²²From now on the people of Israel must not come near the tent of meeting, or they will be responsible for this sin and die.

²³The Levites must do the work connected to the tent of meeting. They will be responsible for any sin regarding it. This will be a permanent law throughout your people's generations. Among the people of Israel they must have no inheritance.

²⁴For the tithes of the people of Israel, which they offer as a contribution to me—it is these that I have given to the Levites as their inheritance. That is why I said to them, 'They must have no inheritance among the people of Israel.'”

²⁵Yahweh spoke to Moses and said,

²⁶“You must speak to the Levites and say to them, 'When you receive from the people of Israel the tenth that I have given to you from them for your inheritance, you will present a contribution from it to Yahweh, a tenth of the tithe.

²⁷Your contribution must be considered by you as if it were a tenth of the grain from the threshing floor or of the production from the winepress.
