Ezekiel 3:16-18

16And it came to pass at the end of seven days, that the word of Jehovah came unto me, saying,

17Son of man, I have appointed thee a watchman unto the house of Israel, and thou shalt hear the word from my mouth, and give them warning from me.

18When I say unto the wicked, Thou shalt certainly die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, that he may live: the same wicked [man] shall die in his iniquity; but his blood will I require at thy hand.
