בראשית, פרק ט״ו, פסוק י״ז

The climax of the Covenant Between the Parts takes place in total darkness, as a dramatic heavenly vision descends to seal an eternal promise between God and Abraham. By this time, the sun had already completely set [רד״ק, רש״י, ביאור יש״ר]. In its wake, a heavy, absolute, and cloudy darkness fell over the area [אבן עזרא, רד״ק, שד״ל, רלב״ג]. Beyond the physical reality of the night, this intense blackness serves as a powerful symbol for the difficult, dark periods of exile that the Israelites would eventually face—times when divine providence would appear to be completely hidden [רד״ק, העמק דבר].

Out of this profound darkness, a wondrous vision suddenly appears: a smoking oven and a flaming torch. The primary approach among commentators is that this was a thick cloud of smoke rising like an oven, with a fierce fire burning inside. This display symbolizes the appearance of the Divine Presence and the glory of God, much like the later revelation at Mount Sinai [רמב״ן, שד״ל, ביאור יש״ר, הכתב והקבלה].

Others see deep historical symbolism in this image. The thick smoke represents the intense troubles and divine concealment of the exile, while the flaming torch symbolizes both the sudden light of salvation that will eventually shine for Israel and the consuming fire that will destroy the enslaving nations [רד״ק, העמק דבר]. Another perspective views the oven as a hint to ultimate judgment, representing the ruin into which those oppressive kingdoms will eventually fall [רש״י, ברטנורא]. Taking a more physical approach, some explain that the smoke actually rose from the animal sacrifices themselves as a heavenly fire came down to consume them [מלבי״ם]. Through this display, the divine power revealed symbolically contains both the capacity to give and to receive, perfectly completing the act of the covenant [רבנו בחיי].

The ritual reaches its peak as the vision passes between the severed animal pieces that had been prepared earlier [ברכת אשר, מחוקקי יהודה]. In the ancient world, the standard method for establishing a covenant and swearing an oath involved cutting animals in half and having the parties walk directly between the pieces [רד״ק, מלבי״ם, אם למקרא]. Therefore, God's passage between the pieces, represented by the flaming torch, serves as the final, decisive action. It officially confirms and establishes His eternal oath to Abraham that his descendants will inherit the land [בכור שור, צאינה וראינה, ביאור שטיינזלץ].
