Joshua 6:2-4

And the LORD said to Joshua: “See! I have given Jericho into your hand, its king, and the mighty men of valor. You shall march around the city, all you men of war; you shall go all around the city once. This you shall do six days. And seven priests shall bear seven trumpets of rams’ horns before the ark. But the seventh day you shall march around the city seven times, and the priests shall blow the trumpets.
