Joshua 21:38-40

Young's Literal Translation

³⁸ And out of the tribe of Gad, the city of refuge [for] the man-slayer, Ramoth in Gilead and its suburbs, and Mahanaim and its suburbs,

³⁹ Heshbon and its suburbs, Jazer and its suburbs -- [in] all four cities.

⁴⁰ All the cities for the sons of Merari, for their families, who are left of the families of the Levites -- their lot is twelve cities.
