And it happened that when the priests carrying the ark came up from the middle of the Jordan, and the soles of the priests' feet {touched dry land}, the waters of the Jordan returned to their place and flowed over all its banks as before.

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

So Joshua son of Nun summoned the priests and said to them, "Take up the ark of the covenant, and let seven priests carry the trumpets of the rams' horns before the ark of Yahweh."
