ירמיהו, פרק ל״א, פסוק ל״ט

In the future, the borders of Jerusalem will experience a significant expansion, requiring the city to be measured anew using precise geographic landmarks. To mark these new dimensions, a special measuring rope, traditionally used for surveying land, will be stretched out across the terrain [מצודת ציון].

The route of this new boundary will extend straight ahead. It will cover the entire former width of the city in order to measure its new, greater length [מצודת דוד], though this extension might also head in a completely different direction [ביאור שטיינזלץ]. The measuring rope will stretch all the way up to the hill of Gareb [מצודת ציון, מנחת שי]. From that point, the boundary line will turn and sweep around [מצודת ציון] toward Goah. Both the hill of Gareb and Goah were well-known locations situated either within or just outside the ancient city of Jerusalem, serving as clear markers for its future growth.
