Joshua 6:17-21

The city and everything that is in it shall be under the ban [that is, designated to be destroyed as a form of tribute] to the LORD; only Rahab the prostitute and all [the people] who are with her in her house shall [be allowed to] live, because she hid and protected the messengers (scouts) whom we sent. But as for you, keep yourselves [away] from the things under the ban [which are to be destroyed], so that you do not covet them and take some of the things under the ban [for personal gain], and put the camp of Israel under the ban (doomed to destruction), and bring disaster upon it. All the silver and gold and articles of bronze and iron are holy (consecrated) to the LORD; they shall go into the treasury of the LORD.” So the people shouted [the battle cry], and the priests blew the trumpets. When the people heard the sound of the trumpet, they raised a great shout and the wall [of Jericho] fell down, so that the sons of Israel went up into the city, every man straight ahead [climbing over the rubble], and they overthrew the city. Then they utterly destroyed everything that was in the city, both man and woman, young and old, and ox and sheep and donkey, with the edge of the sword.
