“Adjoining the territory of Dan,
From the east side
To the west side,
Was one portion.”
Although it is not mentioned, the Mediterranean Sea might have been Asher’s western border. Here it seems to be on both sides of Dan. Asher in Joshua, chapter 19, was west of Naphtali and Zebulun, but here it is mentioned before them. The Israelites never had control of the seacoast towns anyway.
“The fifth lot came out for the tribe of Asher according to its families. Its boundary included Helkath, Hali, Beten, Achshaph, Allammelech, Amad, and Mishal. On the west it touches Carmel and Shihor-libnath, then it turns eastward, it goes to Beth-dagon, and touches Zebulun and the valley of Iphtah-el northward to Beth-emek and Neiel. Then it continues in the north to Cabul, Ebron, Rehob, Hammon, Kanah, as far as Great Sidon. Then the boundary turns to Ramah, reaching to the fortified city of Tyre. Then the boundary turns to Hosah, and it ends at the sea. Mahalab, Achzib, Ummah, Aphek and Rehob were twenty-two towns with their villages. This is the inheritance of the tribe of Asher according to its families, these towns with their villages.”
Asher is the northwestern costal area, north of Manasseh, west of Zebulun and Naphtali, and south of Lebanon. There is no mention of the western border being the Great Sea, but that is assumed. Perhaps they never got control of the sea ports, since that is rarely mentioned. Of the 22 towns mentioned here, Carmel, Tyre, and Sidon are perhaps the most important. It seems like Tyre was never under Israelite control. The following 10 are only mentioned here and nowhere else in the biblical books: Hali, Beten, Allammelech, Amad, Shihor-libnath, Beth-emek, Neiel, Ebron, Mahalab, and Ummah.
