24 You shall observe this thing for an ordinance to you and to your sons forever. 25 It shall happen when you have come to the land which YHWH will give you, as he has promised, that you shall keep this service. 26 It will happen, when your children ask you, ‘What do you mean by this service?’ 27 that you shall say, ‘It is the sacrifice of YHWH’s Passover, who passed over the houses of the children of Israel in Egypt, when he struck the Egyptians, and spared our houses.’” The people bowed their heads and worshiped. Exodus 12:24-27WEB
This passage contains a positive command, directed toward Israel: "Teach this to your children and observe it in every generation".
This passage contributes to an understanding of Holidays because it is about the Passover, Family because it tells us about how parents should teach their children, and Sacarifice because the Passover holiday includes the Passover sacrifice.
The command was fulfilled by Israel, and we can see that they continue to observe the Passover to this day.
For Christians, the command is fulfilled by Jesus, but it has an abiding relevance to us. Jesus is our Passover lamb. During the Passover feast with his disciples, Jesus said to them, "Whenever you do this, do it in remembrance of me" (1 Cor 11:23-25), so that now when we take communion and when our children ask us its meaning, we recall to mind Jesus's sacrifice for our deliverance from death and teach our children about it.
