Description Of Future Passover Feasts
Exodus 12:14-28
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.
In 12:14, the Lord’s instructions change from telling the Israelites what to do on the actual first Passover night to telling them how to commemorate the Passover for all future generations. For the Lord, it is so important that Israel keeps the Passover memory alive that anyone who refuses to celebrate Passover will be cut off from Israel! (See vv. 15 and 19.)
Remember, the exodus is about the formation of God’s people, and central to their identity will be their acknowledgement that they were slaves in Egypt, but that the Lord brought them out with a mighty hand and an outstretched arm. As the account plays out, we will see that this memory works in two ways:
It means that Israel ought to be bold and grateful, because the Lord fights for them and has freed them for a purpose;
But it also means that Israel ought to be humble and merciful, because they know what it’s like to be oppressed.
Here, as the tenth plague is about to strike, the experience of the previous nine plagues seems to have worked—the Lord’s demonstration of His power has changed Israel:
27And 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. [12:27-28]
