I Chronicles 6:18-19, 61, 66-70

The sons of Kohath were Amram, Izhar, Hebron, and Uzziel. The sons of Merari were Mahli and Mushi. Now these are the families of the Levites according to their fathers

To the rest of the family of the tribe of the Kohathites they gave by lot ten cities from half the tribe of Manasseh.

Now some of the families of the sons of Kohath were given cities as their territory from the tribe of Ephraim. And they gave them one of the cities of refuge, Shechem with its common-lands, in the mountains of Ephraim, also Gezer with its common-lands, Jokmeam with its common-lands, Beth Horon with its common-lands, Aijalon with its common-lands, and Gath Rimmon with its common-lands. And from the half-tribe of Manasseh: Aner with its common-lands and Bileam with its common-lands, for the rest of the family of the sons of Kohath.
