Ezekiel 33:4, 8-9

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.

When I say unto the wicked, O wicked man, thou shalt surely die, and thou dost not speak to warn the wicked from his way; that wicked man shall die in his iniquity, but his blood will I require at thy hand. Nevertheless, if thou warn the wicked of his way to turn from it, and he turn not from his way; he shall die in his iniquity, but thou hast delivered thy soul.
