14 “This day shall be for you a memorial day, and you shall keep it as a feast to the Lord; throughout your generations, as a statute forever, you shall keep it as a feast. 15 Seven days you shall eat unleavened bread. On the first day you shall remove leaven out of your houses, for if anyone eats what is leavened, from the first day until the seventh day, that person shall be cut off from Israel. 16 On the first day you shall hold a holy assembly, and on the seventh day a holy assembly. No work shall be done on those days. But what everyone needs to eat, that alone may be prepared by you. 17 And you shall observe the Feast of Unleavened Bread, for on this very day I brought your hosts out of the land of Egypt. Therefore you shall observe this day, throughout your generations, as a statute forever. 18 In the first month, from the fourteenth day of the month at evening, you shall eat unleavened bread until the twenty-first day of the month at evening. 19 For seven days no leaven is to be found in your houses. If anyone eats what is leavened, that person will be cut off from the congregation of Israel, whether he is a sojourner or a native of the land. 20 You shall eat nothing leavened; in all your dwelling places you shall eat unleavened bread.”
21 Then Moses called all the elders of Israel and said to them, “Go and select lambs for yourselves according to your clans, and kill the Passover lamb. 22 Take a bunch of hyssop and dip it in the blood that is in the basin, and touch the lintel and the two doorposts with the blood that is in the basin. None of you shall go out of the door of his house until the morning. 23 For the Lord will pass through to strike the Egyptians, and when he sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and will not allow the destroyer to enter your houses to strike you. 24 You shall observe this rite as a statute for you and for your sons forever. 25 And when you come to the land that the Lord will give you, as he has promised, you shall keep this service. 26 And when your children say to you, ‘What do you mean by this service?’ 27 you shall say, ‘It is the sacrifice of the Lord's Passover, for he passed over the houses of the people of Israel in Egypt, when he struck the Egyptians but spared our houses.’” And the people bowed their heads and worshiped.
28 Then the people of Israel went and did so; as the Lord had commanded Moses and Aaron, so they did.
29 At midnight the Lord struck down all the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the captive who was in the dungeon, and all the firstborn of the livestock. 30 And Pharaoh rose up in the night, he and all his servants and all the Egyptians. And there was a great cry in Egypt, for there was not a house where someone was not dead. 31 Then he summoned Moses and Aaron by night and said, “Up, go out from among my people, both you and the people of Israel; and go, serve the Lord, as you have said. 32 Take your flocks and your herds, as you have said, and be gone, and bless me also!”
33 The Egyptians were urgent with the people to send them out of the land in haste. For they said, “We shall all be dead.” 34 So the people took their dough before it was leavened, their kneading bowls being bound up in their cloaks on their shoulders. 35 The people of Israel had also done as Moses told them, for they had asked the Egyptians for silver and gold jewelry and for clothing. 36 And the Lord had given the people favor in the sight of the Egyptians, so that they let them have what they asked. Thus they plundered the Egyptians. (ESV)
