Numbers 10:8

And Moses sent them to the war, a thousand of every tribe, them and Phinehas the son of Eleazar the priest, to the war, with the holy instruments, and the trumpets to blow in his hand.

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 Shebaniah, and Jehoshaphat, and Nethaneel, and Amasai, and Zechariah, and Benaiah, and Eliezer, the priests, did blow with the trumpets before the ark of God: and Obededom and Jehiah were doorkeepers for the ark.

Benaiah also and Jahaziel the priests with trumpets continually before the ark of the covenant of God.

And, behold, God himself is with us for our captain, and his priests with sounding trumpets to cry alarm against you. O children of Israel, fight ye not against the LORD God of your fathers; for ye shall not prosper. But Jeroboam caused an ambushment to come about behind them: so they were before Judah, and the ambushment was behind them. And when Judah looked back, behold, the battle was before and behind: and they cried unto the LORD, and the priests sounded with the trumpets. Then the men of Judah gave a shout: and as the men of Judah shouted, it came to pass, that God smote Jeroboam and all Israel before Abijah and Judah.
