Joshua 21:7, 34-40

The clan of Merari was allotted twelve towns from the tribes of Reuben, Gad, and Zebulun.

The rest of the Levites—the Merari clan—were given the following towns with their pasturelands from the tribe of Zebulun: Jokneam, Kartah, Dimnah, and Nahalal—four towns. From the tribe of Reuben they received the following towns with their pasturelands: Bezer, Jahaz, Kedemoth, and Mephaath—four towns. From the tribe of Gad they received the following towns with their pasturelands: Ramoth in Gilead (a city of refuge for those who accidentally killed someone), Mahanaim, Heshbon, and Jazer—four towns. So in all, twelve towns were allotted to the clan of Merari.
