Joshua 6:4, 13-16

Have seven priests carry trumpets made from horns of male sheep and have them march in front of the Ark. On the seventh day march around the city seven times and have the priests blow the trumpets as they march.

The seven priests carried the seven trumpets and marched in front of the Ark of the LORD, blowing their trumpets. Soldiers with weapons marched in front of them, and other soldiers walked behind the Ark of the LORD. All this time the priests were blowing their trumpets. So on the second day they marched around the city one time and then went back to camp. They did this every day for six days. On the seventh day they got up at dawn and marched around the city, just as they had on the days before. But on that day they marched around the city seven times. The seventh time around the priests blew their trumpets. Then Joshua gave the command: “Now, shout! The LORD has given you this city!
