Ezekiel 33:7-8

7“Son of man, I have made you a watchman for the people of Israel; so hear the word I speak and give them warning from me. 8When I say to the wicked, ‘You wicked person, you will surely die,’ and you do not speak out to dissuade them from their ways, that wicked person will die for Or in; also in verse 9 their sin, and I will hold you accountable for their blood.
