Ya'akov (Jas) 5:13-18

Is someone among you in trouble? He should pray. Is someone feeling good? He should sing songs of praise. Is someone among you ill? He should call for the elders of the congregation. They will pray for him and rub olive oil on him in the name of the Lord. The prayer offered with trust will heal the one who is ill — the Lord will restore his health; and if he has committed sins, he will be forgiven. Therefore, openly acknowledge your sins to one another, and pray for each other, so that you may be healed. The prayer of a righteous person is powerful and effective. Eliyahu was only a human being like us; yet he prayed fervently that it might not rain, and no rain fell on the Land for three years and six months. Then he prayed again, and heaven gave rain, and the Land produced its crops.
