Leviticus 25:32, 33
As for the cities of the Levites, the Levites always have the right to redeem their houses in the cities they possess. / So whatever belongs to the Levites may be redeemed—a house sold in a city they possess—and must be released in the Jubilee, because the houses in the cities of the Levites are their possession among the Israelites.
Numbers 35:7, 8
The total number of cities you give the Levites will be forty-eight, with their corresponding pasturelands. / The cities that you apportion from the territory of the Israelites should be given to the Levites in proportion to the inheritance of each tribe: more from a larger tribe and less from a smaller one.”
