Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective. (NIV)

Confess to one another therefore your faults (your slips, your false steps, your offenses, your sins) and pray [also] for one another, that you may be healed and restored [to a spiritual tone of mind and heart]. The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available [dynamic in its working]. (AMP)

Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much. (KJV)
