Exodus 12:40-42 Now the sojourn of the children of Israel who lived in Egyptwas four hundred and thirty years. And it came to pass at the end of the four hundred and thirty years—on that very same day—it came to pass that all the armies of the LORD went out from the land of Egypt. It is a night of solemn observance to the LORD for bringing them out of the land of Egypt. This is that night of the LORD, a solemn observance for all the children of Israel throughout their generations.
Genesis 15:2-18 But Abram said, 'Lord GOD, what will You give me, seeing I go childless, and the heir of my house is Eliezer of Damascus?' Then Abram said, 'Look, You have given me no offspring; indeed one born in my house is my heir!' And behold, the word of the LORD came to him, saying, “This one shall not be your heir, but one who will come from your own body shall be your heir.” Then He brought him outside and said, “Look now toward heaven, and count the stars if you are able to number them.” And He said to him, “So shall your descendants be.” And he believed in the LORD, and He accounted it to him for righteousness. 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. And when the vultures came down on the carcasses, Abram drove them away. 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. Now as for you, you shall go to your fathers in peace; you shall be buried at a good old age. But in the fourth generation they shall return here, for the iniquity of the Amorites is not yet complete." 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, saying: "To your descendants I have given this land, from the river of Egypt to the great river, the River Euphrates—
Exodus 12:51 And it came to pass, on that very same day, that the LORD brought the children of Israel out of the land of Egypt according to their armies.
Numbers 33:3 They departed from Rameses in the first month, on the fifteenth day of the first month; on the day after the Passover the children of Israel went out with boldness in the sight of all the Egyptians.

Leviticus 23:6 And on the fifteenth day of the same month is the Feast of Unleavened Bread to the LORD; seven days you must eat unleavened bread.
