The sound of the tribes of Israel's horns destroyed the walls of Old Jericho and conquered Jerusalem. 
Moses died on the journey to the Promised Land, but Joshua took over from him, and between 1400 b.c. and 1000 b.c. the tribes of Israel conquered all the lands north and south of Jerusalem, most famously bringing the walls of Old Jericho tumbling down with the sounds of their horns.
