James 5:14-16

Is any amongst you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord; and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven. Confess your sins to one another and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective.
