In the Bible, the Book of Joshua, quoted here, tells the story of the entry into the Promised Land. After crossing the river Jordan the Israelites faced the walled city of Jericho. For six days they marched around the city. Then on the seventh day, as the Lord had promised, the walls collapsed.
The archaeological remains do not testify to the destruction of Jericho during the 13th century BC. In fact, no significant remains of the time were discovered and it seems the previous Bronze Age settlement was abandoned long before. This absence, however, could also be the result of erosion which has affected most of the archaeological remains.
