בראשית, פרק ח׳, פסוק כ״א

Following the catastrophic devastation of the flood, a profound shift occurs in the relationship between God, humanity, and the material world. As Noah offers his sacrifice, a divine promise of stability emerges from the ruins, rooted in a new acceptance of human nature and its inherent flaws. The description of God perceiving a pleasing odor is expressed in human terms. Rather than implying a physical sense of smell, it signifies that God receives the offering with profound willingness and satisfaction [אבן עזרא, רד״ק, שד״ל, רלב״ג, ביאור יש״ר, קאסוטו]. This sensory imagery represents the acceptance of the offering's spiritual essence, demonstrating a moment where humanity subdues its material desires and fully surrenders its will to serve the Creator [מלבי״ם, הכתב והקבלה, אור החיים]. The offering brings a sense of rest and comfort, calming divine anger and fulfilling God's will [אבן עזרא, רד״ק, הכתב והקבלה, חזקוני, קאסוטו].

In response to this appeasement, God forms a resolve within His heart. The primary approach among commentators is that this represents an internal, absolute divine decree, kept entirely secret and unrevealed to any prophet until Moses eventually recorded it in the Torah [רמב״ן, ספורנו, הטור הארוך, רלב״ג, ביאור יש״ר]. Conversely, another perspective suggests that this communication was not strictly internal. Instead, it involved words of reconciliation and appeasement spoken directly to Noah's heart, meant to comfort him and assure him that the world would never again face such destruction [הכתב והקבלה, מחוקקי יהודה].

This divine assurance is structured in two distinct parts. First, God commits to never again curse the ground because of humanity. He will no longer blight the soil's fertility or corrupt it, as had occurred following the sins of Adam and Cain, or during the flood itself. Second, He guarantees that there will never again be a global extinction of animal life [אבן עזרא, רד״ק, כלי יקר, מלבי״ם, קאסוטו]. The repetition of this commitment is understood by most commentators as a powerful, permanent divine oath [רש״י, מזרחי, שפתי חכמים, ברטנורא, אלשיך, דברי דוד]. Furthermore, it is noted that before the deluge, the earth itself possessed a coarse materiality that predisposed humanity to sin, which is why it was initially cursed. However, once the earth was purified and softened by the floodwaters, it could no longer be blamed for human failings; the responsibility now lies solely with human inclination [כלי יקר].

The reasoning behind this enduring promise rests on the acknowledgment that the inclination of the human heart is evil from its youth. The concept of youth here is linked to the physical act of emerging or shaking free. From the very moment a child leaves its mother's womb, the inclination toward evil is implanted, taking root long before the intellect develops enough to consciously choose good [רמב״ן, רד״ק, רש״י, מזרחי, רבנו בחיי, שפתי כהן, שטיינזלץ]. During these formative years, a person naturally demands independence and casts off restraint, allowing their desires to gradually lead them astray. Only as they mature and age can they harness their intellect to overcome these impulses [ספורנו, הירש, אלשיך].

This rationale marks a profound theological reversal. The very same flawed inclination that previously warranted the annihilation of the flood generation now serves as humanity's defense and a source of divine mercy. God recognizes the inherent weakness of human beings, who are born wild and must continuously battle their own desires. Because this vulnerability is woven into the very fabric of human creation from the start, it is deemed unjust to repeatedly punish the entire natural world for humanity's inevitable stumbles. Consequently, God entirely removes the threat of global annihilation, gifting humanity a stable, permanent reality—a world where people are free to exist, to make mistakes, and ultimately, to correct themselves through their own free will [רמב״ן, שד״ל, מלבי״ם, ביאור יש״ר, קאסוטו, נחלת יעקב, שטיינזלץ].
