Final answer:
Joshua and his army marched around Jericho for 7 days according to the biblical narrative in Joshua 6:1-27 before the walls fell and the Israelites captured the city.
Step-by-step explanation:
In the biblical account found in the Book of Joshua, the Israelites, led by Joshua, circled the fortified city of Jericho for six days. On the seventh day, they marched around the city seven times, and after the seventh circuit, the priests sounded their trumpets, the people shouted, and the walls of Jericho fell, leading to the city's capture. This event is described in Joshua 6:1-27 and is a pivotal moment in the Israelite's conquest of Canaan.
Archaeological evidence shows that Jericho was indeed surrounded by walls in ancient times, but it is difficult to relate the archaeological findings directly to the biblical narrative as no unequivocal evidence of Joshua himself has yet been found. Despite this, Jericho's extensive history of human settlement and the remnants of walls and towers at the site contribute to the fascinating study of ancient civilizations.
