Yosua 21:20-22

21:20 The rest of the Kohathite clans of the Levites were allotted cities from the tribe of Ephraim. 21:21 They assigned them Shechem (a city of refuge for one who committed manslaughter) in the hill country of Ephraim, Gezer, 21:22 Kibzaim, and Beth Horon, along with the grazing areas of each – a total of four cities.
