'Cubits' in the Bible

Then a wind set out from Yahweh, and it drove quails from the west, and he spread [them] out on the camp about a day's journey on one side and about a day's journey on the other, all around the camp, about two cubits on the surface of the land.

"The pasturelands of the cities that you will give to the Levites [will extend] from the wall of the city to [a distance of] a thousand cubits all around.

You will measure outside the city the eastern edge two thousand cubits, for the southern edge two thousand cubits, for the western edge two thousand cubits, and for the northern edge two thousand cubits, with the city in the middle; this will be for them the pasturelands of the cities.
