1 Corinthians 7:5-7

5 Defraud you not one the other, except it be with consent for a time, that you may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.

6 But I speak this by permission, and not of commandment.

7 For I would that all men were even as I myself. But every man has his proper gift of God, one after this manner, and another after that.
