Joshua 6:3-5

King James Version

³ And ye shall compass the city, all ye men of war, and go round about the city once. Thus shalt thou do six days.

⁴ And seven priests shall bear before the ark seven trumpets of rams' horns: and the seventh day ye shall compass the city seven times, and the priests shall blow with the trumpets.

⁵ And it shall come to pass, that when they make a long blast with the ram's horn, and when ye hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall ascend up every man straight before him.
