Numbers 35:4-6

Complete Jewish Bible

⁴ The open land around the cities you give to the L’vi’im is to commence at a line drawn around the city wall 1,500 feet outside it and is to extend outward from there. ⁵ Measure 3,000 feet outward from the city wall to the east, south, west and north, with the city in the center. The space between the 1,500-foot line and the 3,000-foot line will be their open land around the cities. ⁶ The cities you give to the L’vi’im are to be the six cities of refuge to which you permit the person who kills someone to flee to; plus an additional forty-two cities.
