So Joshua son of Nun summoned the priests and said to them, “Take up the ark of the covenant and have seven priests carry seven trumpets in front of the ark of the Lord.”
“ ‘You then crossed the Jordan and came to Jericho. The people of Jericho — as well as the Amorites, Perizzites, Canaanites, Hittites, Girgashites, Hivites, and Jebusites — fought against you, but I handed them over to you.
and commanded the people: “When you see the ark of the covenant of the Lord your God carried by the Levitical priests, you must break camp and follow it.
Then he said to the priests, “Take the ark of the covenant and go on ahead of the people.” So they carried the ark of the covenant and went ahead of them.
and the seven priests carrying seven trumpets marched in front of the ark of the Lord. While the trumpets were blowing, the armed troops went in front of them, and the rear guard went behind the ark of the Lord.
When there is a prolonged blast of the horn and you hear its sound, have all the people give a mighty shout. Then the city wall will collapse, and the people will advance, each man straight ahead.”
After Joshua had spoken to the people, seven priests carrying seven trumpets before the Lord moved forward and blew the trumpets; the ark of the Lord’s covenant followed them.
When the troops returned to the camp, the elders of Israel asked, “Why did the Lord let us be defeated today by the Philistines? Let’s bring the ark of the Lord’s covenant from Shiloh. Then it will go with us and save us from the hand of our enemies.”
