'Righteous One' in the Bible

The whole I have considered in the days of my vanity. There is a righteous one perishing in his righteousness, and there is a wrong-doer prolonging himself in his wrong.

There is a vanity that hath been done upon the earth, that there are righteous ones unto whom it is coming according to the work of the wicked, and there are wicked ones unto whom it is coming according to the work of the righteous. I have said that this also is vanity.
