Joshua 6:16, 20

And it came to pass at the seventh time, when the priests blew with the trumpets, Joshua said unto the people, Shout; for the LORD hath given you the city.

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