1 Corinthians 7:10-12 New Matthew Bible (NMB)
10 To the married command not I, but the Lord, that the wife should not separate herself from the man. 11 But if she separates herself, let her remain unmarried or be reconciled to her husband again. And let not the husband put his wife away from him.
12 To the rest I, and not the Lord, speak. If any brother has a wife who does not believe, if she is content to dwell with him, let him not put her away.
