4 Seven priests shall bear seven htrumpets of irams' horns before the ark. On the seventh day you shall march around the city seven times, and jthe priests shall blow the trumpets.
16 And at the seventh time, when the priests had blown the trumpets, Joshua said to the people, “Shout, for the Lord has given you the city.
20 So the people shouted, and the trumpets were blown. As soon as the people heard the sound of the trumpet, the people shouted a great shout, and rthe wall fell down flat, so that the people went up into the city, every man straight before him, and they captured the city.
