Joshua 6:13-17

And seven priests bearing seven trumpets of rams’ horns before the ark of the LORD went on continually, and blew with the trumpets: and the armed men went before them; but the rereward came after the ark of the LORD, the priests going on, and blowing with the trumpets.

And the second day they compassed the city once, and returned into the camp: so they did six days.

And it came to pass on the seventh day, that they rose early about the dawning of the day, and compassed the city after the same manner seven times: only on that day they compassed the city seven times.

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.
