Joshua 6:17-19

Now the city shall be doomed by the LORD to destruction, it and all who are in it. Only Rahab the harlot shall live, she and all who are with her in the house, because she hid the messengers that we sent. And you, by all means abstain from the accursed things, lest you become accursed when you take of the accursed things, and make the camp of Israel a curse, and trouble it. But all the silver and gold, and vessels of bronze and iron, are consecrated to the LORD; they shall come into the treasury of the LORD.”
