Numbers 18:20-27

²⁰Yahweh said to Aaron, “You shall have no inheritance in their land, neither shall you have any portion among them. I am your portion and your inheritance among 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. Among 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 Yahweh, I have given to the Levites for an inheritance. Therefore I have said to them, ‘Among the children of Israel they shall have no inheritance.’”

²⁵Yahweh spoke to Moses, saying,

²⁶“Moreover you shall speak to the Levites, and tell them, ‘When you take of the children of Israel the tithe which I have given you from them for your inheritance, then you shall offer up a wave offering of it for Yahweh, a tithe of the tithe.

²⁷Your wave offering shall be credited to you, as though it were the grain of the threshing floor, and as the fullness of the wine press.
