God's covenant with Abraham in Genesis 15 is a self-maledictory oath. A malediction is a curse, literally evil speech, and in such an oath a person promises harm to himself if he fails to keep his end of the agreement. The Hebrew speaks of cutting a covenant (compare Jeremiah 34:18), and when God passed through the divided animals, He swore that what had been done to them would happen to Him if He failed to fulfill His promises. Since He could not swear by anything greater, He swore by His own existence (Hebrews 6:13-18), and Abraham was awestruck at how earnest and serious God was. This oath is deeply linked to Christ's crucifixion. The day and time of Jesus' death coincide with the time of the covenant with Abraham, and His blood sealed the New Covenant, which is built upon that covenant. Therefore, had Christ's body been divided or broken, it would have implied that the self-malediction had come to pass, signifying that the Covenant-Maker was paying the price for failure. It was imperative that His blood be shed to seal the New Covenant, and equally essential that His body remain unbroken to satisfy His promises to Abraham. In His sovereignty, God accomplished both without violating either, as John 19:36 and Psalm 34:20 attest.

The covenant God made with Abram in Genesis 15 was a maledictory oath, a rare and very specific kind of vow that researchers say appears in the Bible only once more, in Jeremiah. The one who swore it pledged that if he failed to keep his word, he would pay a severe penalty, apparently death. It was the most serious assurance a person could give. Abraham prepared for it on Nisan 14, the day now called Passover. After meeting Melchizedek, who blessed him and fed him bread and wine, Abraham believed God and was counted righteous. He killed the animals, cut them as God directed, and arranged them on the ground without knowing their purpose. As the sun went down and the 14th ended, darkness fell and a smoking furnace and a burning lamp passed between the pieces. The 15th had begun, the first holy day and the Night to be Much Observed. On that night God swore that His word could be absolutely trusted, and He did it before Abraham's eyes so that Abraham would be impressed with God's seriousness. The oath confirmed the promise of the land and of descendants, and Paul refers to it when he says God confirmed the promise with an oath by which it was impossible for Him to lie. Israel left Egypt exactly 430 years later, on the selfsame day. That exact timing shows God's faithfulness and His control of time.

The timing of Christ's crucifixion on the afternoon of Abib 14 points to a significant event centuries before the Passover in Egypt, aligning with the promises God made to Abraham and the preparations for their covenant. During the daylight portion of the 14th in Abraham's day, a conversation about inheriting the land occurred, followed by Abraham dividing and arranging animals at God's command in preparation for the covenant. This covenant, made in response to Abraham's question about the land, encompasses far more than a geographic location, reflecting all that God had previously promised. If the Creator God was willing to swear to His own destruction with regard to the land, it assures the fulfillment of all other promises as well. Christ's sacrifice, confirming the New Covenant, occurred on the anniversary of God's covenantal promise to Abraham, at the same day and hour, drawing attention to the eternal inheritance promised to Abraham and his spiritual seed.

The concept of a self-maledictory oath, as seen in Genesis 15, is a profound and ancient method of affirming the absolute certainty of one's word. This oath, made by Christ Himself, represents a dire prediction against Himself, forfeiting everything if He fails to keep His word. In this context, Christ was declaring that He would give up salvation and His divinity if He did not fulfill His promise. Such an oath underscores the gravity of the covenant made with Abraham, intertwining the sacrifice of Jesus Christ with this solemn pledge during the events symbolizing Passover and the first day of Unleavened Bread. In Genesis 15, during the preparation for what is observed as the Night To Be Much Observed, the narrative illustrates the 14th as representing the sacrifice of Jesus Christ on Passover day. As the sun dipped below the horizon and the 15th began, marking the Night To Be Much Observed, God uttered the prophecy of 400 years of captivity and the promise of release for Abraham's descendants. This timing aligns precisely with the moment, 430 years later, when Israel departed from Egypt. The passing between the split pieces of the sacrificial animals signifies the actual taking of the self-maledictory oath, with God symbolically signing His life behind the covenant. This act, combined with the presence of the lamp and the smoking furnace, represents the divine purpose and perfect agreement in this transaction, emphasizing the significance of the first day of Unleavened Bread in commemorating God's unwavering commitment and providence.

During the daylight hours of the 14th day of the first month, we reflect on the profound significance of God's covenant with humanity. In the making of a covenant, when the sacrificial animal's parts are separated, the two parties walk through the midst of the parts as an affirmation of the binding agreement. Here, we see the burning torch representing God Himself, guaranteeing the covenant for both parties. This act underscores the divine assurance of the covenant's fulfillment, connecting directly to the events of this sacred day and the night to be much observed after sunset on the 15th. Jesus Christ, as the torch of freedom, alone has guaranteed the New Covenant for all men, liberating us from the deceits of satan and establishing the foundation for all loving relationships.

In the solemn context of God's covenant with Abraham, as recorded in Genesis 15, a profound ritual underscores the gravity of the promise. Covenants of great significance were often sealed by preparing a sacrifice, cutting it into two pieces, and laying them out on the ground. The parties involved would pass between the divided carcass, symbolizing their commitment to the agreement. This act represented a self-maledictory oath, a pledge that they would suffer the same fate as the divided sacrifice—being cut in two—if they failed to uphold their word. They placed their lives at risk, committing themselves to forfeit their life if the covenant was broken. After passing through, the carcass was burned, signifying their acceptance of the terms. In this particular instance, only God is shown passing between the divided sacrifice. This act reveals His utmost seriousness in meeting the requirements of the covenant. It also indicates that He did not hold Abraham or his descendants to the same stringent obligation as He held Himself. The promise, therefore, was to be fulfilled by God's grace, not by human works. The smoking oven and burning torch, symbols of God's presence, likely consumed the sacrifice as He passed through, demonstrating His acceptance. This burning by fire from an invisible source further affirms His commitment, mirroring other instances where He ignited sacrifices from heaven. Thus, the self-maledictory nature of the oath, borne solely by God, emphasizes the unilateral assurance of His faithfulness to the covenant promise.

In the covenant with Abraham, God alone passed between the sacrificial pieces, appearing as a smoking furnace and a burning lamp, demonstrating that the promise did not depend on Abraham's actions. This was a one-sided commitment, guaranteed by God Himself, ensuring it could not be changed or added to. As a self-maledictory oath, God bound Himself to the terms, signifying that He alone bore the responsibility for fulfilling the promise. This unchangeable nature of the covenant, sealed by God's own act, underscores that it rests entirely on His faithfulness. The promise, encompassing both physical land and spiritual blessing to all nations, remains everlasting, revealing the foundation of an eternal relationship with Him.
