Ezekiel 3 (KJV)

18 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 (wickedness); but his blood will I require at thine hand.

20 Again, When a righteous man doth turn from his righteousness, and commit iniquity (wickedness), and I lay a stumbling-block before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand.
