Hebrews 11:30

30.By faith the walls of Jericho fell, etc. As he had before taught us, that the yoke of bondage was by faith broken asunder, so now he tells us, that by the same faith the people gained the possession of the promised land. For at their first entrance the city Jericho stood in their way; it being fortified and almost impregnable, it impeded any farther progress, and they had no means to assail it. The Lord commanded all the men­of­war to go round it once every day, and on the seventh day seven times. It appeared to be a work childish and ridiculous; and yet they obeyed the divine command; nor did they do so in vain, for success according to the promise followed. It is evident, that the walls did not fall through the shout of men, or the sound of trumpets; but because the people believed that the Lord would do what he had promised.

We may also apply this event to our benefit and instruction: for it is not otherwise, than by faith, that we can be freed from the tyranny of the Devil, and be brought to liberty; and by the same faith, it is that we can put to flight our enemies, and that all the strongholds of hell can be demolished.
