When they make a long blast, as is usual in the close of musical sounds. The wall of the city; not all of it, which was not only unnecessary, but inconvenient, and might have given the people better opportunity of escaping; but only a considerable part of it, where the Israelites might fitly enter; for Rahab's house was not overthrown, Joshua 6:22. Flat, Heb. under it, i.e. below the place they stood in; or, in its place: it was not battered down with engines, which would have made part of it fall out of its place; but it fell out without any force, and of its own accord, and therefore in the place it did formerly stand in.

5 And it shall come to pass, that when they make a long blast with the ram's horn, and when ye hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat,a and the people shall ascend up every man straight before him.
