'Righteous Man' in the Bible

Again, when a righteous man doth turn from his righteousness, and commit iniquity, and I lay a stumblingblock before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteous deeds which he hath done shall not be remembered; but his blood will I require at thy hand.

Nevertheless if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall surely live, because he took warning; and thou hast delivered thy soul.

When the righteous man turneth away from his righteousness, and committeth iniquity, and dieth therein; in his iniquity that he hath done shall he die.
