Ezekiel 33:8-9

8Suppose I say to a wicked person, ‘You wicked person, you will certainly die,’ and you say nothing to warn him to change his ways. That wicked person will die because of his sin, and I will hold you responsible for his death.

9But if you warn a wicked person to turn from his ways and he doesn’t turn from them, then he will die because of his sin. However, you will save yourself.
