Ezekiel 33:3-5

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.
