Joshua 6:18
“And ye, in any wise keep yourselves from the accursed thing, lest ye make yourselves accursed, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it.”
And it came to pass at the seventh time, when the priests blew with the trumpets, Joshua said unto the people, Shout; for the Lord hath given you the city.
And the city shall be accursed, even it, and all that are therein, to the Lord: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.
And ye, in any wise keep yourselves from the accursed thing, lest ye make yourselves accursed, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it.
But all the silver, and gold, and vessels of brass and iron, are consecrated unto the Lord: they shall come into the treasury of the Lord.
So the people shouted when the priests blew with the trumpets: and it came to pass, when the people heard the sound of the trumpet, and the people shouted with a great shout, that the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.
