The Walls of Jericho
Seven days round the city, seven trumpets, and a shout. Scroll to watch it.
By faith, the walls of Jericho fell down, after they had been compassed about seven days.
Hebrews 11:30, as St John Chrysostom gives it
For assuredly the sound of trumpets is not able to throw down stones, though one blow for ten thousand years; but Faith can do all things.
John Chrysostom, Homilies on Hebrews XXVII
