Just wondering how this relates to Joshua 6:2

The LORD told Joshua, “Look! I have given Jericho over to your control, along with its kings and valiant soldiers. 3 March around the city, all the soldiers circling the city once. Do this for six days, 4 with seven priests carrying in front of the ark seven trumpets made from rams’ horns. On the seventh day march around the city seven times while the priests blow their trumpets. 5 When they sound a long blast with the ram’s horn, as soon as you hear the sound of the trumpet, then the entire army is to cry out loud, the city wall will collapse, and then all of the soldiers are to charge straight ahead.”
