Joshua 17:9-10

9From the spring of Tappuah, the boundary of Manasseh followed the Kanah Ravine to the Mediterranean Sea. Several towns south of the ravine were inside Manasseh’s territory, but they actually belonged to the tribe of Ephraim.

10In general, however, the land south of the ravine belonged to Ephraim, and the land north of the ravine belonged to Manasseh. Manasseh’s boundary ran along the northern side of the ravine and ended at the Mediterranean Sea. North of Manasseh was the territory of Asher, and to the east was the territory of Issachar.
