'Trumpet' in the Bible

They have blown the trumpet, even to make all ready; but none goeth to the battle: for my wrath is upon all the multitude thereof.

If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;

Then whosoever heareth the sound of the trumpet, and taketh not warning; if the sword come, and take him away, his blood shall be upon his own head.

He heard the sound of the trumpet, and took not warning; his blood shall be upon him. But he that taketh warning shall deliver his soul.

But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.
