As Joshua studies the walls of Jericho, a commander of Heaven’s Armies meets him and gives him God’s plan for how the people are to conquer Jericho. The next day, Joshua has the army march around the walls of Jericho with the priests in front blowing their trumpet. This happened, with no visible result, for 6 days. But on the 7th day, God caused the walls of Jericho to fall down and the people conquered the city sparing only Rahab and her family.
