'Wall' in the Bible

And she let them down by a cord through the window; for her house was upon the city-wall, and she dwelt upon the wall.

And it shall come to pass when they make a long blast with the blast-horn, that all the people on hearing the sound of the trumpet shall shout with a great shout; and the wall of the city shall fall flat, and the people shall go up, each one straight before him.

And the people shouted, and they blew with the trumpets. And it came to pass when the people heard the sound of the trumpets, and the people shouted with a great shout, that the wall fell down flat; and the people went up into the city, each one straight before him, and they took the city.
