1 Corinthians 7:9-11

9 But if they lack self-control, then they should get married—for it is better to marry than burn with desire.

10 These are my instructions to those who are married—in fact not from me but the Lord: The wife should not leave her husband

11 (or if she does, she should not re-marry, or she should return to her husband); and the husband should not leave his wife.[25]
