'Cubits' in the Bible

And there went forth a wind from Jehovah, and brought quails from the sea, and let them fall by the camp, about a day's journey on this side, and a day's journey on the other side, round about the camp, and about two cubits above the face of the earth.

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

And ye shall measure without the city for the east side two thousand cubits, and for the south side two thousand cubits, and for the west side two thousand cubits, and for the north side two thousand cubits, the city being in the midst. This shall be to them the suburbs of the cities.
