Joshua 6:15 “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 has given you the city: 

The Lord spoke to me while reading the verse again about the shout of the people. The ark, the priests with ram horns ( the shofar) were the same BUT at this time the SHABACH (Loud worship) – the shout of the people would bring the walls down.  Praise changes everything done unto the LORD. He wants us to participate in the battle as he give us the victory.
