The Levites were granted cities and surrounding open land to establish a proper infrastructure for their daily routines, carefully addressing their physical and economic needs. The cities themselves were designated strictly for residential use. The Levites were not permitted to alter the nature of their cities by converting residential areas into open, undeveloped land [העמק דבר].
Surrounding these cities were open spaces intended to support their animals and property. This area, extending to an inner radius of a thousand cubits, served specific practical purposes [העמק דבר]. The animals kept here included beasts of burden used for carrying loads and riding, while their property referred to grazing flocks of sheep and cattle [ספורנו].
The primary approach among commentators is that these surrounding lands were meant to provide for all the Levites' ongoing daily needs. On an agricultural level, the open spaces supported additional resources beyond pack animals and flocks, such as beehives and dovecotes [ספורנו]. Furthermore, the land extending to an outer radius of two thousand cubits allowed the Levites to grow fruits and vegetables for immediate consumption. Even though they received agricultural tithes from the rest of the nation, those contributions were typically dried and processed by the time they arrived. The open land gave the Levites the ability to enjoy fresh produce straight from the earth, a state directly associated with vitality and life [העמק דבר].
Beyond food and agriculture, these spaces supported basic health and quality of life. Because wild animals were already accounted for in other categories, the provision for their general living needs is understood as a reference to human vitality and bodily health. A specific, essential need met in these open areas was the washing of clothes. Maintaining clean garments is considered a basic requirement for survival, as wearing dirty clothing leads to suffering, skin irritation, and physical illness [בכור שור, תורה תמימה, רש״ר הירש].
On a conceptual level, the underlying emphasis on life dictates that these areas were dedicated exclusively to the living. Consequently, there was an absolute prohibition against establishing cemeteries within them. When a Levite passed away, he was buried completely outside the borders of the Levite cities and their surrounding lands [חזקוני, משכיל לדוד, תורה תמימה, רש״ר הירש]. The law permitted any possible use of the land that benefited the living, but strictly excluded the burial of the dead [אור החיים]. The only exception to this rule was an accidental murderer who had fled to a Levite city of refuge. If he died while seeking asylum, he was buried within the city itself [אור החיים, תורה תמימה, רש״ר הירש].
