1 Corinthians 7:39

²For the woman that has a husband is bound by law to the husband while he lives, but if the husband dies, she is discharged from the law of the husband. ³So then if, while the husband lives, she is joined to another man, she would be called an adulteress. But if the husband dies, she is free from the law, so that she is no adulteress, though she is joined to another man.

¹⁴Don’t be unequally yoked with unbelievers, for what fellowship do righteousness and iniquity have? Or what fellowship does light have with darkness? ¹⁵What agreement does Christ have with Belial? Or what portion does a believer have with an unbeliever? ¹⁶What agreement does a temple of God have with idols? For you are a temple of the living God. Even as God said, “I will dwell in them and walk in them. I will be their God and they will be my people.”

¹⁰But to the married I command—not I, but the Lord—that the wife not leave her husband

¹⁵Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace.

¹¹Judah has dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah has profaned the holiness of the LORD which he loves, and has married the daughter of a foreign god.

³You shall not make marriages with them. You shall not give your daughter to his son, nor shall you take his daughter for your son. ⁴For that would turn away your sons from following me, that they may serve other gods. So the LORD’s anger would be kindled against you, and he would destroy you quickly.

²God’s sons saw that men’s daughters were beautiful, and they took any that they wanted for themselves as wives.
