'Cubits' in the Bible

Now there went forth a wind from the Lord and it brought quails from the sea, and let them fall [so they flew low] beside the camp, about a day’s journey on this side and on the other side, all around the camp, about two cubits (three feet) deep on the surface of the ground.

“The pasture lands around the cities which you shall give to the Levites shall reach from the wall of the city and outward a thousand cubits (1,500 ft.) around.

You shall also measure outside the city on the east, south, west, and north sides two thousand cubits (3,000 ft.), with the city in the center. This shall belong to the Levites as pasture lands for the cities.
