Does any one among you suffer evil? let him pray. Is any happy? let him sing psalms.
Is any sick among you? let him call to [him] 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 shall heal the sick, and the Lord shall raise him up; and if he be one who has committed sins, it shall be forgiven him.
Confess therefore your offences to one another, and pray for one another, that ye may be healed. [The] fervent supplication of the righteous [man] has much power.

Elias was a man of like passions to us, and he prayed with prayer that it should not rain; and it did not rain upon the earth three years and six months;
and again he prayed, and the heaven gave rain, and the earth caused its fruit to spring forth.
