Hebrews 11:30

By faith the walls of Jericho fell down, after they hade been compassed about for seven days.

Again it was the faith of Israel in the supernatural and invisible that sustained them and produced the victory. Just think of the frustrations of marching around a walled city, the soldiery and priests both in the procession, and the priests carrying the ark of the Lord and blowing on all those ram's horn trumpets! But Jericho fell, just as God promised (Joshua 6). But note that no Israelite could have "seen" how it would fall, or even could fall; and for that matter, after all those intervening centuries, there is no clear view yet as to what, exactly, happened; but FALL the city did and became the first possession of the new Commonwealth of Israel. In this example too there is the factor of all the people participating in the victory; for, if they had not had faith, they would not have followed the Lord's instructions.
