'Wall' in the Bible

Then she let them down by a cord through the window; for her house was on the side of the wall, and she lived on the wall.

It shall be that when they make a long blast with the ram's horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall go up every man straight before him."

So the people shouted, and the priests blew the trumpets. It happened, when the people heard the sound of the trumpet, that the people shouted with a great shout, and the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.
