James 5:16-18 New Revised Standard Version (NRSV)
16 Therefore confess your sins to one another, and pray for one another, so that you may be healed. The prayer of the righteous is powerful and effective. 17 Elijah was a human being like us, and he prayed fervently that it might not rain, and for three years and six months it did not rain on the earth. 18 Then he prayed again, and the heaven gave rain and the earth yielded its harvest.
