1 Coríntios 7

3 And let a man render the love that is due unto his wife;

4 so also the wife to her husband. For the wife hath not authority over her body, but the husband; so also the man hath not authority over his body, but his wife.

5 Defraud not then one the other, unless you both agree for a time, that you may humble yourselves by fasting and by prayer; and return again unto the same will, that Satana may not tempt you on account of the desire of your bodies.
