Ancient Tel of Jericho
After crossing the Jordan River, the first city to be taken during the conquest of the land of Israel was Jericho. G-d commanded the Israelites to encircle the city for 7 days in silence.
On the 7th day, they were to encircle the city seven times with the priests blowing their trumpets as the people raised their voices causing the walls of the city to come tumbling down, in a spectacular victory. In the picture is the ancient Tel of Jericho.
The Bible relates the story:
Joshua 6: 4-5:
“…and on the seventh day, you shall encircle the city seven times, and the priests shall blow with the trumpets.And it shall be that when they make a long blast with the ram's horn when you hear the sound of the trumpet, all the people shall shout a great shout; and the wall of the city shall fall down in its place and the people shall go up, every man straight ahead.”
