When I say to the sinner, thou shalt surely die; if thou speak not to warn, the wicked from his way, the wicked himself shall die in his iniquity; but his blood willI require at thine hand. But if thou forewarn the wicked of his way to turn from it, and he turn not from his way, he shall die in his ungodliness; but thou hast delivered thine own soul.
Jezekiel chapter 3, verses 8 and 9 (The Bible, Old Testament).
