Joshua 21:40

38Out of the tribe of Gad, Ramoth in Gilead with its pasture lands, the city of refuge for the man slayer, and Mahanaim with its pasture lands,

39Heshbon with its pasture lands, Jazer with its pasture lands: four cities in all.

40All these were the cities of the children of Merari according to their families, even the rest of the families of the Levites. Their lot was twelve cities.

41All the cities of the Levites among the possessions of the children of Israel were forty-eight cities with their pasture lands.

42Each of these cities included their pasture lands around them. It was this way with all these cities.
