Joshua 6:13-16

6:13 The seven priests carrying the seven rams’ horns before the ark of the Lord marched along blowing their horns. Armed troops marched ahead of them, while the rear guard followed along behind the ark of the Lord blowing rams’ horns. 6:14 They marched around the city one time on the second day, then returned to the camp. They did this six days in all.

6:15 On the seventh day they were up at the crack of dawn and marched around the city as before – only this time they marched around it seven times. 6:16 The seventh time around, the priests blew the rams’ horns and Joshua told the army, “Give the battle cry, for the Lord is handing the city over to you!
