Numbers 35:3

¹And the Lord spoke to Moses to the west of Moab by Jordan near Jericho, saying,

²Give orders to the children of Israel, and they shall give to the Levites cities to dwell in from the lot of their possession, and they shall give to the Levites the suburbs of the cities round about them.

— Numbers 35:3 —

⁴And the suburbs of the cities which ye shall give to the Levites, shall be from the wall of the city and outward two thousand cubits round about.

⁵And thou shalt measure outside the city on the east side two thousand cubits, and on the south side two thousand cubits, and on the west side two thousand cubits, and on the north side two thousand cubits; and your city shall be in the midst of this, and the suburbs of the cities as described.
