Ezekiel 3:17-18

3:17 “Son of man, I have appointed you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must give them a warning from me. 3:18 When I say to the wicked, “You will certainly die,” and you do not warn him – you do not speak out to warn the wicked to turn from his wicked deed and wicked lifestyle so that he may live – that wicked person will die for his iniquity, but I will hold you accountable for his death.
