Joshua 6:16-18

16And it came to pass the seventh time, when the priests blew with the trumpets, that Joshua said to the people, Shout; for Jehovah has given you the city.

17And the city shall be accursed, it and all that is in it, to Jehovah; only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.

18But in any wise keep from the accursed thing, lest ye make [yourselves] accursed in taking of the accursed thing, and make the camp of Israel a curse, and trouble it.
