Joshua 21:38-41

³⁸And from the tribe of Gad, Ramoth in Gilead, the town where the taker of life might be safe, and Mahanaim with their grass-lands;

³⁹Heshbon and Jazer with their grass-lands, four towns.

⁴⁰All these towns were given to the children of Merari by their families, that is, the rest of the families of the Levites; and their heritage was twelve towns.

⁴¹All the towns of the Levites, among the heritage of the children of Israel, were forty-eight towns with their grass-lands.
