1 Corinthians 14:8

And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies.

And seven priests shall bear before the ark seven trumpets of rams' horns: and the seventh day ye shall compass the city seven times, and the priests shall blow with the trumpets. And it shall come to pass, that when they make a long blast with the ram's horn, and when ye hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall ascend up every man straight before him. And Joshua the son of Nun called the priests, and said unto them, Take up the ark of the covenant, and let seven priests bear seven trumpets of rams' horns before the ark of the LORD. And he said unto the people, Pass on, and compass the city, and let him that is armed pass on before the ark of the LORD. And it came to pass, when Joshua had spoken unto the people, that the seven priests bearing the seven trumpets of rams' horns passed on before the LORD, and blew with the trumpets: and the ark of the covenant of the LORD followed them. And the armed men went before the priests that blew with the trumpets, and the rearward came after the ark, the priests going on, and blowing with the trumpets. And Joshua had commanded the people, saying, Ye shall not shout, nor make any noise with your voice, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout. So the ark of the LORD compassed the city, going about it once: and they came into the camp, and lodged in the camp. And Joshua rose early in the morning, and the priests took up the ark of the LORD. And seven priests bearing seven trumpets of rams' horns before the ark of the LORD went on continually, and blew with the trumpets: and the armed men went before them; but the rearward came after the ark of the LORD, the priests going on, and blowing with the trumpets. And the second day they compassed the city once, and returned into the camp: so they did six days. And it came to pass on the seventh day, that they rose early about the dawning of the day, and compassed the city after the same manner seven times: only on that day they compassed the city seven times. And it came to pass at the seventh time, when the priests blew with the trumpets, Joshua said unto the people, Shout; for the LORD hath given you the city. And the city shall be accursed, even it, and all that are therein, to the LORD: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent. And ye, in any wise keep yourselves from the accursed thing, lest ye make yourselves accursed, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it. But all the silver, and gold, and vessels of brass and iron, are consecrated unto the LORD: they shall come into the treasury of the LORD. So the people shouted when the priests blew with the trumpets: and it came to pass, when the people heard the sound of the trumpet, and the people shouted with a great shout, that the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.

For the builders, every one had his sword girded by his side, and so builded. And he that sounded the trumpet was by me. And I said unto the nobles, and to the rulers, and to the rest of the people, The work is great and large, and we are separated upon the wall, one far from another. In what place therefore ye hear the sound of the trumpet, resort ye thither unto us: our God shall fight for us. So we laboured in the work: and half of them held the spears from the rising of the morning till the stars appeared.

He swalloweth the ground with fierceness and rage: neither believeth he that it is the sound of the trumpet.
