'Warn' in the Bible

If I say to the wicked person, ‘You will surely die,’ but you do not warn him—you don’t speak out to warn him about his wicked way in order to save his life—that wicked person will die for his iniquity. Yet I will hold you responsible for his blood.

But if you warn a wicked person and he does not turn from his wickedness or his wicked way, he will die for his iniquity, but you will have saved your life.

Now if a righteous person turns from his righteousness and practices iniquity, and I put a stumbling block in front of him, he will die. If you did not warn him, he will die because of his sin and the righteous acts he did will not be remembered. Yet I will hold you responsible for his blood.

But if you warn the righteous person that he should not sin, and he does not sin, he will indeed live because he listened to your warning, and you will have saved your life.”

and he sees the sword coming against the land and blows his trumpet to warn the people.

If I say to the wicked, ‘Wicked one, you will surely die,’ but you do not speak out to warn him about his way, that wicked person will die for his iniquity, yet I will hold you responsible for his blood.

But if you warn a wicked person to turn from his way and he doesn’t turn from it, he will die for his iniquity, but you will have saved your life.
