民數記 35:5

另外東量二千肘，南量二千肘，西量二千肘，北量二千肘，為邊界，城在當中；這要歸他們作城邑的郊野。

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.
