'Cubits' in the Bible

And there went forth a wind from Jehovah, and drove quails from the sea, and cast them about the camp, about a day's journey on this side, and about a day's journey on the other side, round about the camp, and about two cubits above the earth.

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.

And ye shall measure, without the city, the east side two thousand cubits, and the south side two thousand cubits, and the west side two thousand cubits, and the north side two thousand cubits, and the city shall be in the midst: they shall have this as suburbs of the cities.
