Ezekiel 3:18 in the King James Version
When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand.
Context
17 “Son of man, I have made you a watchman to the house of Israel. Therefore hear the word from my mouth, and warn them from me.
18 When I tell the wicked, ‘You will surely die;’ and you give him no warning, nor speak to warn the wicked from his wicked way, to save his life, that wicked man will die in his iniquity; but I will require his blood at your hand.
19 Yet if you warn the wicked, and he doesn’t turn from his wickedness, nor from his wicked way, he will die in his iniquity; but you have delivered your soul.”
