Ezekiel 33:8

When I say unto the wicked, O wicked man, thou shalt surelydie, namely, in the absence of a true repentance, becoming subject to a certain death, the earnest of everlasting death; if thou, namely, the prophet, dost not speak to warn the wicked from his way, causing him to forsake his path of iniquity by announcing to him the Lord's warning, that wicked man shall die in his iniquity, for the failure to receive the warning would not take away his guilt, but his blood will I require at thine hand, thus making the prophet directly responsible, on account of his neglect, for the soul of the wicked.
