שמות, פרק ל״ד, פסוק ט״ו

Entering a new land brings the temptation to form political and social alliances with the local inhabitants. However, this natural desire for peaceful relations masks a dangerous psychological and social chain reaction that can end in total spiritual assimilation. The primary approach among commentators is that the warning against making treaties is not merely a standalone rule, but a caution against the inevitable and destructive results that will follow [קאסוטו, ביאור יש״ר, הטור הארוך]. Even if the local inhabitants promise to abandon their idols, they cannot be trusted [אור החיים, מלבי״ם]. Once friendly relations are firmly established, they will inevitably return to their old ways. For this reason, the warning is given specifically as the Israelites prepare to settle the land, rather than during the initial stages of conquest [העמק דבר].

The severity of this assimilation is framed as a profound betrayal. Because the relationship between God and humanity is compared to a marriage, chasing after foreign gods is viewed as spiritual prostitution and a deep breach of trust [רש ר הירש, קאסוטו]. Beyond the spiritual metaphor, this also hints at the actual sexual rituals that were a common part of ancient idol worship [קאסוטו].

The downward spiral truly accelerates through social invitations. As good neighborly relations develop, the locals will naturally invite the Israelites to participate in their personal celebrations and religious feasts [ביאור שטיינזלץ, דברי דוד]. Here lies a profound trap. The primary approach among commentators is that a person might mistakenly believe there is no harm in attending a social gathering, provided they do not actively worship any idols. An individual might even bring their own strictly kosher food and eat only what they brought, innocently thinking they have avoided any wrongdoing [מזרחי, צאינה וראינה, פרדס יוסף, ברכת אשר על התורה]. Yet, merely accepting the invitation and participating in the feast of idol worshipers is viewed by God as if the person has acknowledged their foreign worship and eaten from their sacrifices [רש״י, רמב״ן, מזרחי, גור אריה]. The standard is so exacting that from the very moment the invitation is extended, it is treated as if the sin has already been committed [אור החיים, תורה תמימה על התורה].

This extreme distance is required because a shared meal possesses an immense power to draw hearts closer and break down social barriers. This newfound closeness inevitably leads to the next stages of the chain reaction: intermarriage with the local population, and ultimately, active participation in idol worship [תורה תמימה על התורה, בכור שור, קאסוטו, ספורנו]. Alongside these social dynamics, the reference to the idolater's sacrifice also serves as the basis for a sweeping legal prohibition against eating meat slaughtered by a non-Jew. According to this view, the very act of slaughter performed by an idol worshiper is fundamentally corrupt and invalid, even if the physical process was done without any practical flaw [אור החיים].
