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.
Defraud ye not - namely, of the conjugal "due" (1 Corinthians 7:3: cf. Septuagint, Exodus 21:10).
Give yourselves - literally, be at leisure for; be free from interruptions for; on some special 'season' х kairon (G2540)]; as before Easter (Exodus 19:15; Joel 2:16; Zechariah 7:3). Fasting and prayer. A B Delta G f g, Vulgate, omit "fasting and;" 'Aleph (') C support the words. Interpolated by ascetics.
Come together. 'Aleph (') A B C Delta G read 'be together,' namely, in the regular married state.
Satan - who thrusts in his temptations to unholy thoughts amidst the holiest exercises.
For your incontinency - because of your inability to "contain" (1 Corinthians 7:9) natural propensities, which Satan takes advantage of.
