Joshua 16:8-12

The border went out from Tappuah westward unto the river Kanah; and the goings out thereof were at the sea. This is the inheritance of the tribe of the children of Ephraim by their families.

And the separate cities for the children of Ephraim were among the inheritance of the children of Manasseh, all the cities with their villages.

And they drave not out the Canaanites that dwelt in Gezer: but the Canaanites dwell among the Ephraimites unto this day, and serve under tribute.
