Joshua 6:4 WBT

²  And the LORD said to Joshua, See, I have given into thy hand Jericho, and its king, [and] the mighty men of valor.

³  And ye shall compass the city, all [ye] men of war, [and] go round 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 every man straight before him.

⁶  And Joshua the son of Nun called the priests, and said to them, Take up the ark of the covenant, and let seven priests bear seven trumpets of rams' horns before the ark of the LORD.
