'Wall' in the Bible

And the messenger of Jehovah standeth in a narrow path of the vineyards -- a wall on this side and a wall on that --

and the ass seeth the messenger of Jehovah, and is pressed unto the wall, and presseth Balaam's foot unto the wall, and he addeth to smite her;

And the suburbs of the cities which ye give to the Levites are, from the wall of the city and without, a thousand cubits round about.
