Hallel (, "Praise") is a Jewish prayer, a verbatim recitation from Psalms which is recited by observant Jews on Jewish holidays as an act of praise and thanksgiving. Holy days Hallel consists of six Psalms (113–118), which are recited as a unit, on joyous occasions including the Three Pilgrimage Festivals mentioned in the Torah, Passover (Pesach), Shavuot, and Sukkot, as well as at Hanukkah and Rosh Chodesh (beginning of the new month). Hallel is recited during the evening prayers on the first (and, outside Israel, second) night of Pesach, except by Lithuanian and German Jews, and by all communities during the Passover Seder service. According to the Talmud, there was a dispute between the school of Hillel and the school of Shammai regarding the reading of Hallel on Pesach. According to the school of Shammai, only the first psalm (Ps. 113) should be read before the meal, whereas the school of Hillel advocated reading the first two psalms (Ps. 113 and 114). The remaining Psalms would be said after the Grace After Meals (as is usually the case, the halacha follows the school of Hillel). Although Hallel generally refers only to the aforementioned psalms, the Talmud also refers to Psalm 136 as "the Great Hallel". Each verse of Psalm 136 concludes with the refrain "for his mercy endures forever" and it contains mention of twenty-six acts of Divine kindness and sustenance for the world. It is recited at the Pesach Seder after the standard Hallel is completed. It is also said in the expanded Pesukei dezimra on the morning of Shabbat and festivals. In the Talmudic era, if rain fell on the morning of a fast day that was declared in response to a drought, this was seen as a sign of Divine favor, in which case "the Great Hallel" was added in the afternoon prayers. There is mention in some references that this Psalm may also be used antiphonally in Temple worship. On Rosh Hashanah and Yom Kippur, Hallel is not said at all, because as the Talmud states (Arachin 10b): "Is it seemly for the king to be sitting on His Throne of Judgment, with the Books of Life and Death open before Him, and for the people to sing joyful praises to Him?" Pesach, like Sukkot, has the structure of "main holiday", followed by "Intermediate Days" (Chol HaMoed), followed by "main holiday". Since Pesach involved only a
