Only matzah
On all nights we eat leavened and unleavened — why on this night only matzah?
The Seder is the order of the festival night. Its central commandment is to tell the children the story of the Exodus, so that the memory of freedom is not broken in any generation.
The heart of the Seder: following the Haggadah, the Exodus story is retold, beginning with the children's questions and answering them through the night.
The “bread of affliction” and of freedom: the unleavened bread eaten in memory of the hasty departure from Egypt.
Bitter herbs — the taste of slavery. They are eaten to feel the bitterness out of which the people went free.
Over the night four cups of wine are drunk — for the four promises of redemption given to the people.
The youngest at the table asks four questions — Ma Nishtana. The telling begins with them: everything unusual at the table calls for explanation.
On all nights we eat leavened and unleavened — why on this night only matzah?
On all nights we eat any vegetables — why on this night maror, bitter herbs?
On all nights we do not dip even once — why on this night twice?
On all nights we eat sitting or leaning — why on this night does everyone recline, like free people?

This is the bread of affliction… let all who are hungry come and eat.
