10 To the married I give this command (not I, but the Lord): A wife must not separate from her husband. 11 But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
10 And unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband: 11 But and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife.
English Standard Version
10 To the married I give this charge (not I, but the Lord): the wife should not separate from her husband 11 (but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.
10 And if you are married, stay married. This is the Master's command, not mine. 11 If a wife should leave her husband, she must either remain single or else come back and make things right with him. And a husband has no right to get rid of his wife.
New King James Version
10 Now to the married I command, yet not I but the Lord: A wife is not to depart from her husband. 11 But even if she does depart, let her remain unmarried or be reconciled to her husband. And a husband is not to divorce his wife.
New Living Translation
10 But for those who are married, I have a command that comes not from me, but from the Lord. A wife must not leave her husband. 11 But if she does leave him, let her remain single or else be reconciled to him. And the husband must not leave his wife.
Matthew Henry's Commentary on 1 Corinthians 7:10-11
Man and wife must not separate for any other cause than what Christ allows. Divorce, at that time, was very common among both Jews and Gentiles, on very slight pretexts. Marriage is a Divine institution; and is an engagement for life, by God's appointment. We are bound, as much as in us lies, to live peaceably with all men, Romans 12:18, therefore to promote the peace and comfort of our nearest relatives, though unbelievers. It should be the labour and study of those who are married, to make each other as easy and happy as possible. Should a Christian desert a husband or wife, when there is opportunity to give the greatest proof of love? Stay, and labour heartily for the conversion of thy relative. In every state and relation the Lord has called us to peace; and every thing should be done to promote harmony, as far as truth and holiness will permit.
