《圣经》(《The Holy Bible》)约书亚记 Joshua 6:4-5:
七个祭司要拿七个羊角走在约柜前。到第七日，你们要绕城七次，祭司也要吹角。他们吹的角声拖长，你们听见角声，众百姓要大声呼喊，城墙就必塌陷，各人都要往前直上。
Have seven priests carry trumpets of rams’ horns in front of the ark. On the seventh day, march around the city seven times, with the priests blowing the trumpets. When you hear them sound a long blast on the trumpets, have the whole army give a loud shout; then the wall of the city will collapse and the army will go up, everyone straight in.”
