Ezekiel 33:7-8

EJ2000(i) 7 So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth and warn them from me. 8 When I say unto 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 for his sin; but I will require his blood at thine hand.
