Joshua 21:39

Kedemoth with her suburbs, and Mephaath with her suburbs; four cities.

And out of the tribe of Gad, Ramoth in Gilead with her suburbs, to be a city of refuge for the slayer; and Mahanaim with her suburbs,

So all the cities for the children of Merari by their families, which were remaining of the families of the Levites, were by their lot twelve cities.

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