'Warn' in the Bible

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.

But as for you, if you warn the wicked and he does not turn from his wicked deed and from his wicked lifestyle, he will die for his iniquity but you will have saved your own life.

However, if you warn the righteous person not to sin, and he does not sin, he will certainly live because he was warned, and you will have saved your own life."

But suppose the watchman sees the sword coming and does not blow the trumpet to warn the people. Then the sword comes and takes one of their lives. He is swept away for his iniquity, but I will hold the watchman accountable for that person's death.'

"As for you, son of man, I have made you a watchman for the house of Israel. Whenever you hear a word from my mouth, you must warn them on my behalf.

When I say to the wicked, 'O wicked man, you must certainly die,' and you do not warn the wicked about his behavior, the wicked man will die for his iniquity, but I will hold you accountable for his death.

But if you warn the wicked man to change his behavior, and he refuses to change, he will die for his iniquity, but you have saved your own life.
