Rahab is a key character who helps the Israelites from within the city of Jericho. She recognizes that their God is unlike any other and aids them in their conquest, acting as an insider who supports Joshua and his people during the siege.

Joshua leads the Israelites by following God's unusual battle plan, which involves marching around the city walls once a day for seven days, with priests carrying the Ark of the Covenant. On the seventh day, after the procession, the people blow horns and shout, causing the walls of Jericho to collapse.

Besides Joshua, the film features Moses, who appoints Joshua as his successor before his death; Rahab, who aids the Israelites; Salmon and Caleb, who are part of the Israelite community; and female characters such as Sharon and Achsah, who contribute to the story's interpersonal dynamics.

The Israelites face the challenge of an impenetrable fortress with massive walls and fierce soldiers. The king of Jericho chooses to hide behind the walls rather than confront them directly. Inside the city, there is tension and scheming among the people of Jericho as they try to defend their land and remove the Israelites.

The Ark of the Covenant is carried by priests during the seven-day procession around Jericho. It symbolizes God's presence and leadership, and its role is central to the miraculous plan that leads to the collapse of the city walls, demonstrating the power of faith and divine intervention.
