'Cubits' in the Bible

Just then, a wind burst forth from the LORD, who brought quails from the sea and spread them all around the camp, about a day's journey in each direction, completely encircling the camp about two cubits deep on top of the ground!

The grazing lands that you are to reserve for use by the descendants of Levi are to extend 1,000 cubits from the walls of the town.

You are to measure from outside the wall of the town on the east side 2,000 cubits, on the south side 2,000 cubits, on the west side 2,000 cubits, and on the north side 2,000 cubits, with the town placed at the center. This reserved area is to serve as grazing land for their towns.
