'Western' in the Bible

The western border was the Mediterranean Sea. These were the borders of the tribe of Judah and its clans.

Ephraim's territory was to the south, and Manasseh's to the north. The sea was Manasseh's western border and their territory touched Asher on the north and Issachar on the east.

It then turned on the west side southward from the hill near Beth Horon on the south and extended to Kiriath Baal (that is, Kiriath Jearim), a city belonging to the tribe of Judah. This is the western border.
