1 Corinthians 7:5
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.
1 Corinthians 12:21
And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
