ויקרא, פרק י״ח, פסוק כ״ח

The Land of Israel is endowed with a profound spiritual sensitivity, possessing a nature that simply cannot tolerate moral ugliness or impurity. It is portrayed as a living entity that actively cleanses itself by emptying out and expelling sinners from its borders [ביאור שטיינזלץ, רד״צ הופמן, רש״י]. This unique sensitivity exists because the land is not governed by intermediary angels or heavenly ministers like other regions of the world. Instead, it is guided directly by God, making it uniquely incapable of enduring idolatry and sexual immorality [רא״ש בשם הרמב״ן].

To emphasize the urgency of this reality, the cautionary message is delivered much like a doctor urgently warning a patient to avoid harmful food, pointing to the tragic fate of a previous patient who consumed the same thing [אור החיים]. The Israelites are compared to a prince with a delicate stomach, accustomed only to the finest foods; the moment he consumes something repulsive, his body immediately rejects it. While the collective nations that inhabited the land before the Israelites were allowed to remain for a long time despite their sins until their measure of guilt was entirely full, the Israelites are held to a much more sensitive standard. If they sin, the land will reject them immediately [רש״י, שפתי חכמים, רד״צ הופמן]. In fact, the expulsion of the previous nations is described as an event happening in the immediate present, highlighting how the land is always on the verge of purging impurity [אבן עזרא, חזקוני, אבי עזר, רד״צ הופמן, הכתב והקבלה].

The primary approach among commentators is that the warning of being expelled like the previous nations is not a promise of a lenient punishment, but rather an alert of severe escalation. The Israelites are warned not to assume that their worst fate would merely be physical displacement. Because they have entered into a direct covenant with God, their punishment for defiling the land would be far more severe, resulting in spiritual excision and the loss of the soul [פני דוד, רבנו בחיי, ריב״א, חזקוני, חומת אנך, הדר זקנים, תולדות יצחק, רא״ש]. A distinction is made between the sins of individuals and the sins of the nation as a whole. If only individuals commit these grave sins, they face spiritual excision. However, if the entire nation becomes entrenched in such behavior, the collective punishment is exile [רלב״ג, העמק דבר].

The tragedy of this collective exile is that strangers will eventually come and settle in the Israelites' place [תורה תמימה]. Consequently, the land will lose its holy purpose, the Divine Presence will depart, and the era of the Temple and prophecy will cease [ביאור יש״ר]. Yet, within this severe punishment lies a profound measure of mercy. By sending the people into exile, God pours His wrath upon the physical wood and stones of the land rather than completely destroying the nation itself, thereby ensuring that a remnant of the people will always survive [פני דוד].
