'Righteous Man' in the Bible

Again, When a righteous man turns from his righteousness, and commits iniquity, and I lay a stumblingblock before him, he shall die: because you have not given him warning, he shall die in his sin, and his righteousness which he has done shall not be remembered; but his blood will I require at your hand.

Nevertheless if you warn the righteous man, that the righteous sins not, and he does not sin, he shall surely live, because he is warned; also you have delivered your soul.

When a righteous man turns away from his righteousness, and commits iniquity, and dies in them; for his iniquity that he has done shall he die.
