ויקרא, פרק י״ח, פסוק כ״ה

A person's moral choices do not remain confined to their private life; they echo outward, directly shaping their physical and spiritual surroundings. When severe offenses become routine and socially accepted, they corrupt reality and pollute the environment [שטיינזלץ]. The resulting defilement of the land is not merely poetic imagery, but a literal reality in which human sin damages the world [אם למקרא]. Specifically, acts of sexual immorality are directly responsible for causing the physical and spiritual contamination of the earth [ספורנו].

Typically, moral duties regarding sexual boundaries are personal obligations tied to the human body, seemingly independent of any specific geographic location. However, the Land of Israel operates under different spiritual rules. While other nations of the world are placed under the guidance of angelic ministers, the Land of Israel is God's direct inheritance, reserved exclusively for His people. Because of its supreme holiness and close proximity to the Divine Presence, the land is exceptionally sensitive. It simply cannot tolerate the presence of idol worshipers or those who engage in sexual immorality [רמב״ן, הטור הארוך, אם למקרא].

Because of this severe contamination, a divine decree is issued to purge the sin from the land [ביאור יש״ר]. Once the heavenly account book is opened, the full debt is collected [אדרת אליהו]. A spiritual perspective suggests that every evil action generates a destructive force. In this view, the sin itself is appointed to punish the sinner, bringing about a relentless sequence of consequences [אור החיים]. Another approach traces the land's involvement back to the dawn of creation. Originally, the earth produced coarse, murky matter instead of pure substance, and this fundamental flaw planted the seeds of physical lust within humanity. Consequently, when people surrender to immoral desires, the earth itself is viewed as an accomplice and shares in the punishment [כלי יקר].

The land's ultimate reaction to this deep moral pollution is one of physical rejection. It is compared to a sick person whose body is repulsed by spoiled food, vomiting it out in absolute disgust with no desire to ever consume it again [אבן עזרא, חזקוני, כלי יקר, אדרת אליהו]. The Land of Israel is fundamentally incapable of sustaining unrepentant sinners [פרדס יוסף]. To cleanse itself, it forcefully expels them through mechanisms like natural disasters or military conquest [שטיינזלץ].

Although the expulsion of the Canaanites is described as an event that had already occurred, even before they were actually driven out, this reflects the absolute certainty of the divine will. Once the decree of expulsion was finalized in heaven, the inhabitants were considered as if they had already been expelled [רמב״ן, הטור הארוך]. Alternatively, this past perspective hints at ancient Canaanite tribes that were already destroyed and purged from the land during the time of Abraham because of their wickedness, while the remaining inhabitants simply waited for their measure of guilt to reach its limit in the days of Joshua [ביאור יש״ר].
