'Horn' in the Bible

And he will send out his angels with a great sound of a horn, and they will get his saints together from the four winds, from one end of heaven to the other.

Lifting up a horn of salvation for us in the house of his servant David,

For if the war-horn gives out an uncertain note, who will get ready for the fight?

In a second, in the shutting of an eye, at the sound of the last horn: for at that sound the dead will come again, free for ever from the power of death, and we will be changed.

Because the Lord himself will come down from heaven with a word of authority, with the voice of the chief angel, with the sound of a horn: and the dead in Christ will come to life first;

And to the sound of a horn, and the voice of words, the hearers of which made request that not a word more might be said to them:

I was in the Spirit on the Lord's day, and a great voice at my back, as of a horn, came to my ears,

After these things I saw a door open in heaven, and the first voice came to my ears, like the sound of a horn, saying, Come up here, and I will make clear to you the things which are to come.

Saying to the sixth angel who had the horn, Make free the four angels who are chained at the great river Euphrates.

But in the days of the voice of the seventh angel, when the sound of his horn is about to come, then will the secret of God be complete, of which he gave the good news to his servants the prophets.
