Joshua 6:11-15

So he had the ark of the Lord taken around the city, circling it once; then they came into the camp and spent the night in the camp.

Now Joshua got up early in the morning, and the priests took up the ark of the Lord.

Then the seven priests carrying the seven trumpets of rams’ horns in front of the ark of the Lord went on continually, and blew the trumpets; and the armed men went ahead of them, and the rear guard came after the ark of the Lord, while they continued to blow the trumpets.

So the second day they marched around the city once and returned to the camp; they did the same for six days.

Then on the seventh day they got up early at the dawning of the day and marched around the city in the same way seven times; only on that day did they march around the city seven times.
