"Also seven priests shall carry seven trumpets of rams' horns before the ark; then on the seventh day you shall march around the city seven times, and the priests shall blow the trumpets.
"It shall be that when they make a long blast with the ram's horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city will fall down flat, and the people will go up every man straight ahead."
So Joshua the son of Nun called the priests and said to them, "Take up the ark of the covenant, and let seven priests carry seven trumpets of rams' horns before the ark of the LORD ."
And it was so, that when Joshua had spoken to the people, the seven priests carrying the seven trumpets of rams' horns before the LORD went forward and blew the trumpets; and the ark of the covenant of the LORD followed them.
The seven priests carrying the seven trumpets of rams' horns before the ark of the LORD went on continually, and blew the trumpets; and the armed men went before them and the rear guard came after the ark of the LORD , while they continued to blow the trumpets.
