Ezekiel 33:7-9

7“So you, son of man: I have made you a watchman for the house of Israel; therefore you shall hear a word from My mouth and warn them for Me.

8When I say to the wicked, ‘O wicked man, you shall surely die!’ and you do not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood I will require at your hand.

9Nevertheless if you warn the wicked to turn from his way, and he does not turn from his way, he shall die in his iniquity; but you have delivered your soul.
