So it came about on the third day, when it was morning, that there were thunder and lightning flashes and a thick cloud over the mountain and a very loud trumpet sound, so that all the people who were in the camp trembled.

When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him with thunder.

And all the people were watching and hearing the thunder and the lightning flashes, and the sound of the trumpet, and the mountain smoking; and when the people saw it all, they trembled and stood at a distance.

“Speak to the sons of Israel, saying, ‘In the seventh month on the first of the month you shall have a rest, a reminder by blowing of trumpets, a holy convocation.

The Silver Trumpets

The Lord spoke further to Moses, saying,

“Make yourself two trumpets of silver, you shall make them of hammered work; and you shall use them for summoning the congregation and breaking camp.

When convening the assembly, however, you shall blow the trumpets without sounding an alarm.

The sons of Aaron, moreover, the priests, shall blow the trumpets; and this shall be a permanent statute for you throughout your generations.

And when you go to war in your land against the enemy who attacks you, then you shall sound an alarm with the trumpets, so that you will be thought of by the Lord your God, and be saved from your enemies.

Also on the day of your joy and at your appointed feasts, and on the first days of your months, you shall blow the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; and they shall be as a reminder of you before your God. I am the Lord your God.”

Offerings of the Seventh Month

‘Now in the seventh month, on the first day of the month, you shall have a holy assembly; you shall do no laborious work. It will be to you a day for blowing trumpets.

And Moses sent them, a thousand from each tribe, to the war, and Phinehas the son of Eleazar the priest, to the war with them, and the holy implements and the trumpets for the alarm in his hand.

Also seven priests shall carry seven trumpets of rams’ horns in front of the ark; then on the seventh day you shall march around the city seven times, and the priests shall blow the trumpets.

It shall be that when they make a long blast with the ram’s horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city will fall down flat, and the people shall go up, everyone straight ahead.”

So Joshua the son of Nun called the priests and said to them, “Take up the ark of the covenant, and have seven priests carry seven trumpets of rams’ horns in front of the ark of the Lord.”

And it was so, that when Joshua had spoken to the people, the seven priests carrying the seven trumpets of rams’ horns before the Lord went forward and blew the trumpets; and the ark of the covenant of the Lord followed them.

And the armed men went ahead of the priests who blew the trumpets, and the rear guard came after the ark, while they continued to blow the trumpets.

Then the seven priests carrying the seven trumpets of rams’ horns in front of the ark of the Lord went on continually, and blew the trumpets; and the armed men went ahead of them, and the rear guard came after the ark of the Lord, while they continued to blow the trumpets.

And at the seventh time, when the priests blew the trumpets, Joshua said to the people, “Shout! For the Lord has given you the city.

So the people shouted, and the priests blew the trumpets; and when the people heard the sound of the trumpet, the people shouted with a great shout, and the wall fell down flat, so that the people went up into the city, everyone straight ahead, and they took the city.

And when he arrived, he blew the trumpet in the hill country of Ephraim; and the sons of Israel went down with him from the hill country, and he was leading them.

So the Spirit of the Lord covered Gideon like clothing; and he blew a trumpet, and the Abiezrites were called together to follow him.

So the three hundred men took the people’s provisions and their trumpets in their hands. And Gideon dismissed all the other men of Israel, each to his tent, but retained the three hundred men; and the camp of Midian was below him in the valley.

And he divided the three hundred men into three units, and he put trumpets and empty pitchers into the hands of all of them, with torches inside the pitchers.

When I and all who are with me blow the trumpet, then you also blow the trumpets around the entire camp and say, ‘For the Lord and for Gideon!’”
