What Does Genesis 15:17 Mean?

When the sun had set and darkness had fallen, a smoking firepot with a blazing torch appeared and passed between the pieces. The covenant ceremony reaches its climax in one of the most dramatic images in the Old Testament. After the long afternoon vigil, after the deep sleep and the darkness and the prophetic word, the divine presence appears in two symbolic forms: a smoking firepot and a blazing torch. These were not unusual objects in the ancient world; they were ordinary tools of fire and light. Their extraordinary significance is in what they do: they pass between the divided animals.

The divine presence moving through the corridor of the divided animals is the covenant ratification. But critically, only the divine presence passes through; Abram does not. In the standard covenant-cutting ceremony, both parties passed between the pieces, each invoking the self-curse: "May I be cut like these animals if I break this covenant." Here, God passes through alone. The covenant is not bilateral, with both parties bearing equal obligation. It is a unilateral divine grant, with God alone bearing the covenant burden. If the covenant is broken, God alone will Bear the consequences.

The smoking firepot and blazing torch anticipate the pillar of cloud and fire that will guide Israel through the Exodus and wilderness. The God who appears to Abram in fire in the night vision is the same God who will appear in fire at Sinai and lead Israel through the wilderness by fire at night. The fire of the divine presence is the consistent visual signature of covenant encounter from Abram's vision to the Day of Pentecost when Jesus fulfilled the covenant by sending the Spirit as tongues of fire. The fire that passed between the pieces was the promise the Spirit fulfilled at Pentecost.
