John Wesley on Joshua 6:5

The wall - Not all of it; which was unnecessary, 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, ver.22. Flat - Heb. under it, it was not battered down with engines which would have made part of it fall out of its place; but it fell of its own accord, and therefore in the place it did formerly stand in. God chose this way, to try the faith and obedience of the people: whether they would observe a precept, which to human policy seemed foolish, and believe a promise, which seemed impossible to be performed: whether they could patiently bear the reproaches of their enemies, and patiently wait for the salvation of God. Thus by faith, not by force, the walls of Jericho fell down.
