1 Corinthians 7:5

5 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.

Ver. 5. To fasting and prayer ] Preces nobis ieiuniis alendum et quasi saginandum. Fasting days are soul fatting days: prayer is edged and winged thereby.

That Satan tempt you not ] The temptation is strong to fornication, stronger to adultery. Watch therefore. Our nature is catching this way; and once in, it is not so easy to come off. This is a searing sin, Hosea 4:11 ; Ephesians 4:19 .
