Numbers 35:2-4

Darby Translation

² Command the children of Israel, that of the inheritance of their possession they give unto the Levites cities to dwell in; and a suburb for the cities round about them shall ye give unto the Levites.

³ And the cities shall they have to dwell in, and their suburbs shall be for their cattle, and for their goods, and for all their beasts.

⁴ And the suburbs of the cities that ye shall give unto the Levites shall be from the walls of the city outward, a thousand cubits round about.
