Haggadah (Hebrew) 'telling'
After the Bible, the Haggadah is the most widely read Jewish text. Although many commonly refer to the entire book as the Haggadah, the term "Haggadah" technically refers to the middle part of the Haggadah, or the "Maggid" section. The content and order are based upon Exodus 13:8, and the mitzvah to recount the story of the Exodus is the basis for the Haggadah. It is read during the Jewish Passover. The Malbim Haggadah is the commentary of the Haggadah, and it appeared in Hebrew 100 years ago, and was recently translated to English. If you want to read it in greater detail, check out http://ohr.edu/yhiy/article.php/802. Formal title: Medrash Haggadah. The Haggadah is made up of 6 sections:
1. V'higadita l'vincha --"And you shall relate to your child"
The purpose of this Mitzvah (the recounting of the exodus) is not only to appreciate the deliverance of the Jews from Egypt by Hashem our G-d, but also to ensure that future generations do not forget what G-d did for us.
2. Bayom Hahu -- "On That Day"
On the 15th of Nissan, the retelling of the exodus must take place- “when matzah and maror are in front of you.”
The actual re-telling of the story of the Exodus. So, first there is a description of the obligation “V’higadita l’vincha,” and then we are told when to say it “Bayom Hahu,” and now we are given a script. The Haggadah cites each verse and shows how the details of the Exodus are inherent in each word within Deuteronomy 26:5-8
4. Ba'avur Zeh --"Because of This"
Pesach (the Paschal offering), matzah, and maror are all explained here, because, according to Rabbi Gamliel, if they are not, then one has not fulfilled the obligation to recount the Exodus.
5. Asah Hashem Li--"Hashem Acted For Me"
This explains why we must recount the events surrounding the Exodus as if we had personally left Egypt ourselves- because Hashem (G-d) acted for me, as an individual.
6. B'tzeisi M'Mitzrayim--"When I Came Forth From Egypt"
This section introduces and contains the Hallel of the Seder, the psalms of praise to G-d for the miracles of the redemption from Egypt.
