Ezekiel 3:18-20

18I may say to a wicked person, “Your punishment will be death.” Then you must warn that person. You must tell him to stop doing wicked things so that he may save his life. If you do not tell the wicked person this, he will die because of his sins. But I will say that you are guilty, as if you had killed him yourself.

19So you must warn the wicked person. If you warn him, he still may not stop doing wicked things. Then that wicked person will die because of his sins. But you will have saved your own life.

20A righteous person may stop doing things that are right. He may start to do bad things. Then I will put him in danger. He will die as punishment for his sins. I will not remember the good things that he did. But if you have not warned him of the danger, I will say that you are guilty. It is as if you killed him yourself.
