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

And he said unto them, This kind can come forth by nothing, but by prayer and fasting.

And she was a widow of about fourscore and four years, which departed not from the temple, but served God with fastings and prayers night and day.

Defraud 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.
