24 And you are to keep this as an order to you and to your sons for ever. 25 And when you come into the land which the Lord will make yours, as he gave his word, you are to keep this act of worship. 26 And when your children say to you, What is the reason of this act of worship? 27 Then you will say, This is the offering of the Lord's Passover; for he went over the houses of the children of Israel in Egypt, when he sent death on the Egyptians, and kept our families safe. And the people gave worship with bent heads.

Commentary on Exodus 12:21-28
(Read Exodus 12:21-28)
That night, when the first-born were to be destroyed, no Israelite must stir out of doors till called to march out of Egypt. Their safety was owing to the blood of sprinkling. If they put themselves from under the protection of that, it was at their peril. They must stay within, to wait for the salvation of the Lord; it is good to do so. In after-times they should carefully teach their children the meaning of this service. It is good for children to ask about the things of God; they that ask for the way will find it. The keeping of this solemnity every year was, 1. To look backward, that they might remember what great things God had done for them and their fathers. Old mercies, to ourselves, or to our fathers, must not be forgotten, that God may be praised, and our faith in him encouraged. 2. It was designed to look forward, as an earnest of the great sacrifice of the Lamb of God in the fulness of time. Christ our passover was sacrificed for us; his death was our life.
