Leviticus 25:34

Now Yahweh spoke to Moses in the plains of Moab by the Jordan opposite Jericho, saying,

“Now as for the cities which you shall give from the possession of the sons of Israel, you shall take more from the larger, and you shall take less from the smaller; each shall give some of his cities to the Levites in proportion to his possession which he inherits.”

Also for the sons of Aaron the priests who were in the pasture lands of their cities, or in each and every city, there were men who were designated by name to distribute portions to every male among the priests and to everyone genealogically recorded among the Levites.

“Moreover, they shall not sell or exchange any of it, or let this choice portion of land pass over to another; for it is holy to Yahweh.
