According to the Hebrew Bible the Israelites took over Jericho because: a. the walls of Jericho fell after Joshua's army marched over and over around the city blowing their trumpets. The Israelites marched around the walls for 6 days and on the seventh day they marched seven times around the walls and then the priests blew their ram's horns and the marching men raised a great shout and the walls of the city fell.
