Ezekiel 3:17 (KJV)

Then I came to them of the captivity at Tel–abib, that dwelt by the river of Chebar, and I sat where they sat, and remained there astonished among them seven days.

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

Son of man, I have made thee a watchman unto the house of Israel: therefore hear the word at my mouth, and give them warning from me.

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.

Yet if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul.
