1 Corinthians 7:10-13

Haweis(i) 10 But to the married not I command, but the Lord, That the wife be not separated from the husband: 11 and even if she should be separated, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife. 12 But to the others I speak, not the Lord, If any brother hath a wife unbelieving, yet she chuseth to dwell with him, let him not put her away. 13 And the wife which hath a husband not a believer, and he chuses to dwell with her, let her not put him away.
