The account of Israel's exodus from Egypt provides a clue to the significance of the afternoon of the 14th—the time when the Messiah was crucified.
The Israelites had killed the lambs after sunset as the 14th began, smearing the blood on the doorposts of their houses. They then roasted and ate the lambs, burning the remains. At midnight the Death Angel passed over, slaying the firstborn of those not under the blood. The Israelites remained in their houses until daybreak, after which they finished spoiling the Egyptians, then all 2-3 million of them traveled to Goshen. Numbers 33:3 records that they departed Rameses on the 15th day—“the day after the Passover”—and Deuteronomy 16:1 verifies that they left at night.
The Exodus, then, began at night, as Abib/Nisan 15 began. This “night of solemn observance” is the “very same day” or the “self-same day” (King James Version [KJV]) as an event that happened 430 years before—to the exact day. That prior event is the initial covenant God made with Abraham:
Then He said to him, “I am the LORD, who brought you out of Ur of the Chaldeans, to give you this land to inherit it.” And he said, “Lord GOD, how shall I know that I will inherit it?” So He said to him, “Bring Me a three-year-old heifer, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon.” Then he brought all these to Him and cut them in two, down the middle, and placed each piece opposite the other; but he did not cut the birds in two. . . .
Now when the sun was going down, a deep sleep fell upon Abram; and behold, horror and great darkness fell upon him. Then He said to Abram: “Know certainly that your descendants will be strangers in a land that is not theirs, and will serve them, and they will afflict them four hundred years. And also the nation whom they serve I will judge; afterward they shall come out with great possessions. . . .
And it came to pass, when the sun went down and it was dark, that behold, there appeared a smoking oven and a burning torch that passed between those pieces. On the same day the LORD made a covenant with Abram. . . . (Genesis 15:7-10, 12-14, 17-18)
In verse 13, God's states that Abraham's descendants would be afflicted, yet finally delivered. This is that “very same day” to which Exodus 12:41-42 refers—the beginning of the 15th day, just after sunset.
