1 Corinthians 7:10-12 Amplified Bible (AMP)
10 But to the [a]married [believers] I give instructions—not I, but the Lord—that the wife is not to separate from her husband, 11 (but even if she does leave him, let her remain single or else be [b]reconciled to her husband) and that the husband should not leave his wife.
12 To the [c]rest I declare—I, not the Lord [since Jesus did not discuss this]—that if any [believing] brother has a wife who does not believe [in Christ], and she consents to live with him, he must not leave her.
1 Corinthians 7:10-12 New International Version (NIV)
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.
12 To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her.
