Joshua 6:2
And the LORD said unto Joshua, See, I have given into thine hand Jericho, and the king thereof, and the mighty men of valour.14And the second day they compassed the city once, and returned into the camp: so they did six days.
20So 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.
