James 5:13-16

13Is any among you afflicted? let him pray. Is any merry? let him sing psalms. 14Is any sick among you? 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: 15And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.

16Confess your trespasses one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
