Bible Verses About Trumpet: Giving alarm in cases of danger

Son of man, speak to the children of thy people, and say to them: When I bring the sword upon a land, if the people of the land take a man, one of their meanest, and make him a watchman over them:

And he sees the sword coming upon the land, and sound the trumpet, and tell the people:

Then he that heareth the sound of the trumpet, whosoever he be, and doth not look to himself, if the sword come, and cut him off: his blood shall be upon his own head.

He heard the sound of the trumpet, and did not look to himself, his blood shall be upon him: but if he look to himself, he shall save his life.

And if the watchman see the sword coming, and sound not the trumpet: and the people look not to themselves, and the sword come, and cut off a soul from among them: he indeed is taken away in his iniquity, but I will require his blood at the hand of the watchman.
