Joshua 6:16, 20

And the seventh time it happened, when the priests blew the trumpets, that Joshua said to the people: “Shout, for the LORD has given you the city!

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