Commentaries:
Genesis 15:10 and 17 show us a small portion of the ancient practice of making serious covenants. Those making the covenant prepared a sacrifice by dividing animals or fowl in two, then both parties passed between the divided carcasses. This symbolized the seriousness of their intentions in that the divided carcasses represented what would happen to them if they did not keep their oath! They placed their lives at risk. The carcasses were then burned, symbolizing their acceptance.
The smoking oven and burning torch symbolize God. In many instances in the Bible, God represents Himself through the image of fire (i.e., the burning bush and the pillar of fire). The sacrifice in Genesis 15 is interesting in that only God passes between the divided carcasses because, in reality, this is an oath of only one party, God, to keep His promise. In this specific case, Abraham has agreed to nothing, but God has bound Himself with utmost seriousness to meet the requirements of His promise in full. This promise will be fulfilled only because of God's character and grace.
The 14th thus signifies the ratification of the promise by sacrifice, and the 15th, what it accomplishes by providing visible evidence of God's faithfulness (e.g., the Israelites go free).

Now it was dark. In the antitype, the Firstborn, Christ, is in His grave. Therefore, time-wise we are now into Abib 15. We have come all the way from ben ha arbayim, at the beginning of Abib 14, and the events progressing one after the other through Genesis 15. At verse 17, Abib 15—the First Day of Unleavened Bread—begins.
What occurs in Genesis 15:17 is the actual beginning of the Night To Be Much Observed. Exodus 12:41-42 merely records a fulfillment of this first Night To Be Much Observed. Genesis 15:17 is the point from which the 430 years began, and they ended in Exodus 12:41—down to the very day. It was the beginning of Abib 15.
This is a night of great significance in the salvation story of God's people. Because the firstborn of the Egyptians had been slaughtered, and the descendants of Abraham had been released from their slavery to leave Egypt, the firstborn of Egypt thus become types of the Firstborn, Jesus Christ—the Sacrifice for our sins that enslave us to spiritual Egypt.

The Wavesheaf and the Selfsame Day
For the events of Genesis 15:17-21, the sun has gone down, and it is dark. In the crucifixion sequence, by dark the Son was in His grave. This is now the 15th of Nisan, the day that became the first day of Unleavened Bread, the part known as the Night To Be Much Observed, "the selfsame day" of Exodus 12:41. Numbers 33:3 confirms Israel left Egypt on the 15th of Nisan, but Exodus 12:42 specifically states Israel began its departure at night, and God names that night the "Night To Be Much Observed." Its significance is that, because the firstborn of the Egyptians have been slain, the descendents of Abraham are released from their bondage and free to leave Egypt. The firstborn of Egypt thus become a type of the True Firstborn, Jesus Christ, the sacrifice for our sins that enslave us to spiritual Egypt.

This prophecy is fulfilled exactly 430 years later (Exodus 12:40-41; Galatians 3:17) when Israel left Egypt as the sun set ending the 14th day of Abib and beginning the 15th. God says to us in Isaiah 46:10, "My counsel shall stand." This is why the prophecies ring with such positive assurance. No puny man or angel, no mighty army of angels, nor all nations of men can stop Him from acting exactly how, when, where, and in whom He purposes.

In Genesis 15:8-17, Abraham asks for evidence that God will follow through. He receives a command to prepare a sacrifice and an additional prophecy concerning his family's future. Genesis 15:12 shows that he made the sacrifice during the daylight part of the 14th. By this sacrifice, God ratifies His promise to Abraham.
Many have wondered why Christ was sacrificed during the daylight portion of the 14th, in the afternoon, rather than at its beginning and more in alignment with the Passover service in the twilight portion of the 14th. This reveals why. Even as He ratified His covenant of promise with Abraham by this sacrifice, Christ's sacrifice provides the ratification of the New Covenant. Christ's sacrifice, by God's decree, had to align with the ratification of His covenant of promise with Abraham. In Christ's sacrifice, death, and burial, God's draws together in one event the main elements of both the covenant of promise with Abraham and the Passover.
Notice especially how close this chronological alignment is. Verse 12 specifically states, "When the sun was going down." Thus, this sacrifice, like Christ's, took place in the afternoon. In the late afternoon, a great darkness and horror fell upon Abraham, allowing him to experience a small taste of the horror Christ faced in His crucifixion when God forsook Him. In addition, Moses inserts a detail that is not so readily apparent at Christ's crucifixion: that Abraham had to beat off some vultures. Vile birds are a Bible symbol of demons. This detail suggests that a great spiritual battle occurred, during which the demons taunted and persecuted Christ to induce Him to give up. He had to fight them off alone because the Father had forsaken Him.
