1 Corinthians 7:3-13 YLT

3 to the wife let the husband the due benevolence render, and in like manner also the wife to the husband;
4 the wife over her own body hath not authority, but the husband; and, in like manner also, the husband over his own body hath not authority, but the wife.
5 Defraud not one another, except by consent for a time, that ye may be free for fasting and prayer, and again may come together, that the Adversary may not tempt you because of your incontinence;
6 and this I say by way of concurrence -- not of command,
7 for I wish all men to be even as I myself [am]; but each his own gift hath of God, one indeed thus, and one thus.
8 And I say to the unmarried and to the widows: it is good for them if they may remain even as I [am];
9 and if they have not continence -- let them marry, for it is better to marry than to burn;
10 and to the married I announce -- not I, but the Lord -- let not a wife separate from a husband:
11 but and if she may separate, let her remain unmarried, or to the husband let her be reconciled, and let not a husband send away a wife.
12 And to the rest I speak -- not the Lord -- if any brother hath a wife unbelieving, and she is pleased to dwell with him, let him not send her away;
13 and a woman who hath a husband unbelieving, and he is pleased to dwell with her, let her not send him away;
