On the first night of Pesach, we begin the Arbit prayer with the recitation of the 107 th chapter of Tehillim. This chapter opens with the exclamation, "Hodu L'Hashem Ki Tob, Ki Le'olam Hasdo" – "Thank G-d, for He is good, for His kindness is eternal." The selection of this chapter as the introduction to the night of the seder is very significant, because it encapsulates the essence of this night. The seder is what we might call the Jewish "thanksgiving dinner," as it revolves around the theme of gratitude, thanking Hashem for all He has done for us. In fact, this chapter of Tehillim proceeds to describe the four situations which require a person to bring a Korban Toda – a thanksgiving sacrifice in the Bet Ha'mikdash, or, nowadays, to recite Birkat Ha'gomel, thanking Hashem for saving him. These four situations are a sea voyage, a trip through the desert, imprisonment, and serious illness. A person who emerges from any of these four perilous situations is required to bring a Korban Toda to express his gratitude to Hashem. Our ancestors experienced all four situations. They were released from bondage, from their "imprisonment" in Egypt, and the Sages teach that when they departed Egypt, all their physical ailments from which they suffered as a result of slavery were cured. They then crossed the sea and the desert. This is one of the reasons given for the obligation to drink four cups of wine at the seder. We drink one cup to express gratitude for each of these dangerous conditions from which our forefathers were rescued. Appropriately, therefore, we begin the Arbit service on this night with the chapter of Tehillim that speaks of the obligation to express gratitude to Hashem for these four forms of redemption, all of which are celebrated on the night of the seder. The Maharal of Prague (Rav Yehuda Loew, 1512-1609) asserted that this theme of the seder explains why we refer to the text read on this night with the term "Haggadah." The source of this term, the Maharal writes, is a Misva which has a surprising connection to the seder experience – the Misva of Bikkurim, which requires a farmer to bring the first of his orchard's fruits that ripen to the Bet Ha'mikdash and give them to a Kohen. When he arrived in the Bet Ha'mikdash, the farmer was to pronounce a special text dictated in the Torah (Debarim 26), a text commonly referred to as "Mikra Bikkurim." In this proclamation, the farmer would briefly recall his ancestors' period of slavery in Egypt, how they cried to Hashem, and how He miraculously brought them to freedom. The four verses of Mikra Bikkurim comprise the text that we use at the seder as the focal point of our discussion of Yesiat Misrayim (the Exodus from Egypt). Rather than go through the entire narrative of the Egyptian bondage and the Exodus, we go through the brief account of Mikra Bikkurim, carefully analyzing each phrase of this short text. The Maharal notes that the first words the Torah requires the farmer to declare upon arriving in the Bet Ha'mikdash with his fruits are "Higadeti Hayom L'Hashem Elokecha." The Aramaic Targum Yerushalmi translation of the Torah renders this verse as, "I give thanks and praise to Hashem your G-d." It thus turns out that the word "Higadeti," which we would normally translate as "I have told," actually means expressing praise and gratitude. And it is for this reason, the Maharal writes, that we refer to the text of the Pesach seder as the "Haggadah" – because this is the text we use to express our gratitude to Hashem, which is what the seder experience is all about. In the introduction to the Maggid section of the Haggadah, we announce, "Ve'chol Ha'marbeh Hareh Zeh Meshubah" – the more one speaks about Yesiat Misrayim on this night, the more praiseworthy he is. The Maharal writes that when it comes to expressing gratitude, the more the better. Saying "thank you" to someone who did us a favor might be enough to discharge our obligation, but we can and should do better than that. When expressing appreciation, we should be detailed and specific, and not hold back. The more gratitude we show, the better. There is so much negativity and cynicism all around us. There are so many people who criticize and complain about everything, who focus on what's wrong and then constantly talk about it. Let us counter this negativity with positivity, by indulging in gratitude, in appreciation, by regularly praising and being thankful for all the good there is. Of course, we live in an imperfect world, where there is always something to complain about. But we also live in a wonderful world with so much to be grateful for. And this should be our focus. May the upcoming night of gratitude motivate us to always see and direct our attention toward the goodness all around us and all that is right in our world, so we will live with joy and contentment even as we do our small part to address the world's imperfections in an effort to correct them.
