Joshua 6:17-21

17And the city and all that is within it shall be devoted to the LORD for destruction. Only Rahab the prostitute and all who are with her in her house shall live, because she hid the messengers whom we sent. 18But you, keep yourselves from the things devoted to destruction, lest when you have devoted them you take any of the devoted things and make the camp of Israel a thing for destruction and bring trouble upon it. 19But all silver and gold, and every vessel of bronze and iron, are holy to the LORD; they shall go into the treasury of the LORD.” 20So the people shouted, and the trumpets were blown. As soon as the people heard the sound of the trumpet, the people shouted 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 captured the city. 21Then they devoted all in the city to destruction, both men and women, young and old, oxen, sheep, and donkeys, with the edge of the sword.
