"And unto the families of the children of Merari, the rest of the Levites, out of the tribe of Zebulun, Jokneam with its suburbs, and Kartah with its suburbs, Dimnah with its suburbs, Nahalal with its suburbs; four cities. And out of the tribe of Reuben, Bezer with its suburbs, and Jahaz with its suburbs, Kedemoth with its suburbs, and Mephaath with its suburbs; four cities. And out of the tribe of Gad, Ramoth in Gilead with its suburbs, the city of refuge for the manslayer, and Mahanaim with its suburbs, Heshbon with its suburbs, Jazer with its suburbs; four cities in all. All [these were] the cities of the children of Merari according to their families, even the rest of the families of the Levites; and their lot was twelve cities." — Joshua 21:34-40 (ASV)
