Joshua 6:16-20

Then on the seventh time, when the kohanim blew the shofarot, Joshua ordered the people, “Shout! For ADONAI has given you the city! But the city will be under the ban of destruction—it and all that is in it belong to ADONAI. Only Rahab the harlot will live, she and all who are with her in the house, because she hid the scouts that we sent. But you, just keep yourselves from the things under the ban. Otherwise you would make yourselves accursed by taking of the things under the ban, and so you would make the camp of Israel accursed and bring trouble on it. All the silver and gold and vessels of bronze and iron are holy to ADONAI, and must go into the treasury of ADONAI.” So when the shofarot blew, the people shouted. When the people heard the sound of the shofar, the people shouted a loud shout—and the wall fell down flat! So the people went up into the city, everyone straight ahead, and they captured the city.
