'Righteous Man' in the Bible

He that receiveth a prophet as a prophet, shall have a prophet's reward: and he that receiveth a righteous man as such, shall receive a righteous man's reward.

(And while he was sitting on the tribunal, his wife sent to him, saying, Have nothing to do with that righteous man: for I have suffered much in a dream to day on his account.)

And they said, Cornelius the centurion, a righteous man, and one that feareth God, and of a good character among all the nation of the Jews, hath been warned from God by an holy angel, to send for thee to his house, and to hear what thou shalt say.

Confess your faults one to another, and pray for one another, that ye may be healed: the fervent prayer of a righteous man availeth much.
