'Warned' in the Bible

Yet if you have warned the wicked and he does not turn from his wickedness or from his wicked way, he shall die in his iniquity; but you have delivered yourself.

Again, when a righteous man turns away from his righteousness and commits iniquity, and I place an obstacle before him, he will die; since you have not warned him, he shall die in his sin, and his righteous deeds which he has done shall not be remembered; but his blood I will require at your hand.

However, if you have warned the righteous man that the righteous should not sin and he does not sin, he shall surely live because he took warning; and you have delivered yourself.”

But if the watchman sees the sword coming and does not blow the trumpet and the people are not warned, and a sword comes and takes a person from them, he is taken away in his iniquity; but his blood I will require from the watchman’s hand.’
