Numbers 35:5
And ye shall measure from without 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 the city shall be in the midst: this shall be to them the suburbs of the cities — an alternative measurement system specifies that the suburbs extend two thousand cubits in each cardinal direction from the city-center, a larger zone that encompasses the one-thousand-cubit inner pasture-lands. The city is centered within this larger square, ensuring complete environmental provision.
