Parallel
Joshua 6:5
Brenton's English Septuagint · Berean Standard Bible
And it shall be [that] when ye shall sound with the trumpet, all the people shall shout together. And when they have shouted, the walls of the city shall fall of themselves; and all the people shall enter, each one rushing direct into the city.
And when there is a long blast of the ram’s horn and you hear its sound, have all the people give a mighty shout. Then the wall of the city will collapse (note: Or fall under itself or fall flat; similarly in verse 20) and all your people will charge straight into the city.”
