'Trumpet' in the Bible

They have blown the trumpet and made all ready, but none goeth to the battle; for my fierce anger is upon all the multitude thereof.

if he see the sword coming upon the land, and 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 is upon him: whereas had he taken warning, he would have delivered his soul.

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