17:21Howbeit this kind goeth not out but by prayer and fasting.

14:23And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.

7:5Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
