It happened, when the priests who bore the ark of the covenant of Yahweh had come up out of the middle of the Jordan, and the soles of the priests' feet were lifted up to the dry ground, that the waters of the Jordan returned to their place, and went over all its banks, as before.

Seven priests shall bear seven trumpets of rams' horns before the ark. On the seventh day, you shall march around the city seven times, and the priests shall blow the trumpets.

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 Yahweh."
