In the Beginning: The Bible Stories

Jericho (1x18)

:

When the people of Israel approach the Promised Land of Jericho, they see a fortress city surrounded by impregnable walls. It is impossible for anyone to enter the city, thinks Joshua, the son of Moses. Then God's messenger says to him, "I will give you Jericho, its king, and his warriors. Walk around the city for seven days. Let seven priests blow trumpets made from rams' horns. The wall will collapse on the seventh day." So the people of Israel follow those words and begin to walk around the walls blowing the horns. Jericho's army is puzzled at their behavior.
