במדבר, פרק ל״ה, פסוק ד׳

The allocation of cities to the Levites involved more than just providing places to live; it required meticulous environmental and urban planning. The open spaces surrounding these cities were carefully designed to serve the practical needs of the residents while preserving the aesthetic beauty and overall quality of life in the community. The designated open space extending outward from the city wall [ביאור שטיינזלץ] formed a complete perimeter around the settlement [העמק דבר]. This area functioned as a vital buffer, providing room for pasture, storage, and the daily necessities of the inhabitants, while strictly prohibiting burials. It also served as an area for leisure and walking, helped keep unpleasant odors away from the residential areas, and provided designated spots to gather manure for agricultural use [רלב״ג].

Although the measurement technically began at the city wall, some maintain that a small empty courtyard space of just over seventy cubits was left immediately adjacent to the wall as an integral part of the city, with the formal measurement of a thousand cubits beginning only beyond it [תורה תמימה, רש״ר הירש]. Another perspective suggests that in ancient times, the immediate area by the city gate was considered the street, and the measurement extended from this street toward the outer limits [הכתב והקבלה].

A central issue in understanding this urban layout arises from an apparent contradiction regarding the size of the open space, as one measurement dictates a thousand cubits while another requires two thousand. The primary approach among commentators resolves this by envisioning the land divided into two distinct concentric bands, granting the Levites a total of two thousand cubits in every direction. The inner thousand cubits, which touched the city wall [משכיל לדוד], were kept completely clear of houses and crops to maintain the city's visual appeal, while the outer thousand cubits were allocated for fields and vineyards [רש״י, רלב״ג, מזרחי]. The distinct purposes of these zones were strictly maintained, and it was forbidden to convert an open aesthetic space into an agricultural field or vice versa [רלב״ג]. Expanding on this zoned approach, another viewpoint suggests the Levites actually received a total of three thousand cubits, dedicating the first thousand to open space and the remaining two thousand to agriculture [הכתב והקבלה בשם הרמב״ם].

A completely different perspective offers a mathematical model based on a square. In this view, a thousand cubits were measured outward in all directions, and the reference to two thousand cubits describes the total length of the square enclosing the city rather than an additional outward distance. This assumes the city itself measured exactly a thousand by a thousand cubits; adding five hundred cubits of open space to each side yields an overall square of two thousand by two thousand cubits. The areas directly facing the walls remained clear, while the four corners of the square were utilized for agriculture [הטור הארוך בשם הרמב״ן]. However, many strongly reject this rigid calculation, arguing that the Levite cities were originally existing Canaanite settlements of varying sizes. Therefore, they contend the two thousand cubits must have been measured outward regardless of the city's actual dimensions [שד״ל, הכתב והקבלה, גור אריה].

Further solutions propose unique geometric layouts or buffer zones to reconcile the measurements. One such idea is that the initial thousand cubits formed a perfect circle around the city, and the subsequent two thousand cubits were measured in straight lines to create a square enclosing that circle [פענח רזא]. Finally, another approach maintains that the entire allocated area was kept completely free of agriculture. According to this layout, a thousand cubits were measured outside the city wall, while the two thousand cubit measurement began from the innermost line of houses. This effectively created an empty buffer zone of a thousand cubits inside the city walls and another thousand cubits outside [שד״ל].
