The answer is: Thou shalt not commit adultery

Exo 20:14

The seventh commandment, "Thou shalt not commit adultery," holds a significant place in the foundation of ethical relationships in the Exodus narrative, revealing much about societal values in ancient Israel. Adultery was not merely about the betrayal of trust between partners, but it symbolized a struggle against the sanctity of community and family structure—both hallmarks of the Israelite identity.

In the larger context, the Ten Commandments emerged after the Israelites' exodus from Egypt—a pivotal moment of liberation and identity formation. They were meant to guide this fledgling society into a future based on moral integrity and mutual respect. Each commandment echoes core principles of justice and fidelity essential for a thriving community.

Interestingly, the Hebrew word traditionally translated as "adultery," לוֹטַ (n'efs), emphasizes the deeper emotional and spiritual bond that marriage represents. In fact, the act of adultery wasn’t just seen as treachery towards one’s spouse; it risked fracturing communal trust.

Kids might be intrigued to know how important marriage was viewed. Ancient Israelites often tied marriage closely with divine expectations. Some references in the scriptures equate unfaithfulness with idolatry—a kind of betrayal not just to a partner, but to God, reflecting those dual attachments of relationship and spirituality. So, as you think about this commandment, remember it's about much more than individual relationships—it's about the vitality and cohesiveness of the entire community!
