Ezekiel 33:7-9

7So thou, O son of man, I have set thee a watchman to the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. 8When I say to the wicked, O wicked man, thou shalt surely die; if 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. 9Nevertheless, if thou shalt warn the wicked of his way to turn from it; if he will not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul.
