יהושע, פרק י״ט, פסוק כ״ו

Mapping the territory of the Tribe of Asher reveals a distinct coastal boundary defined by prominent natural landmarks. The western edge of their land runs directly along the Mediterranean Sea, stretching down to a southern limit at Mount Carmel. The boundary physically meets the mountain right where it stands beside the water [מצודת דוד, ביאור שטיינזלץ]. This coastal meeting point serves as the absolute southern tip of the tribe's land [מלבי״ם].

From this southern anchor at Mount Carmel, Asher's western border spans upward along the coastline until it reaches its northern limit at a stream flowing into the sea [מלבי״ם, ביאור שטיינזלץ]. This northern river is identified by a distinct, two-part name to set it apart from the famous river of Egypt, which is known in the Bible by only the first half of that title. The second part of the river's name, meaning "white," likely points to the white glass that was historically manufactured in its waters [מלבי״ם].
