יהושע, פרק י״ט, פסוק י״ח

Mapping out the land for the tribe of Issachar involves a precise network of cities and geographical landmarks to establish its borders. The path of the boundary line begins its course at the city of Jezreel [מצודת דוד]. Situated near the Jezreel Valley [ביאור שטיינזלץ], this city marks the southern edge of Issachar's western boundary. Jezreel and the city of Chesulloth sit exactly at the southwestern corner of the tribe's designated territory [מלבי״ם].

Because of this specific placement, Issachar's border runs extremely close to the land given to the tribe of Manasseh, as the Jezreel Valley itself was actually part of Manasseh's territory [מצודת דוד]. From its starting point in the southwestern corner, the boundary line travels from Jezreel toward Chesulloth [מצודת דוד]. It then pivots, heading upward from south to north along the western edge of Issachar's land [מלבי״ם].
