'Cities of the Levites' in the Bible

Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.

And if a man purchase of the Levites, then the house that was sold, and the city of his possession, shall go out in the year of jubile: for the houses of the cities of the Levites are their possession among the children of Israel.

"Command the children of Israel, that they give unto the Levites, of the inheritance of their possession, cities to dwell in. And ye shall give also unto the cities of the Levites, suburbs round about them.

All the cities of the Levites within the possession of the children of Israel were forty and eight cities with their suburbs.
