Thematic Bible: Alarm of, given by trumpets

The same man, when he seeth the sword come upon the land, shall blow the trumpet, and warn the people.

For he heard the sound of the trumpet, and would not take heed, therefore his blood be upon him. But if he will receive warning, he shall save his life. read more.
