In the third major section of the Tanakh (Hebrew Bible), which is called Ketuvim ("The Writings"), there are five relatively short biblical books that are grouped together and known collectively in the Jewish tradition as "The Five Scrolls" (Hebrew: Hamesh Megillot or Chamesh Megillos). These five books are:
An early testimony that these five scrolls were grouped together is in the Midrash Rabba. This midrash was compiled on the Pentateuch and on the Five Scrolls.
All five of these megillot ("scrolls") are traditionally read publicly in the synagogue over the course of the year in many Jewish communities. In common printed editions of the Tanakh they appear in the order that they are read in the synagogue on holidays (beginning with Passover), thus:
When read in the synagogue, these five books are sung with cantillation (see below). In most communities, Esther is the only book accompanied by blessings before and after. But certain communities adopted the custom of the Vilna Gaon to recite blessings before the other four megillot (besides Esther) as well. Similarly, the very term megillah ("scroll") is most widely used for the book of Esther, even though it is applied the rest as well.
As indicated above, however, only two of the megillot are traditionally read in all Jewish communities, namely: Esther on Purim and Lamentations on the Ninth of Av. The practice to read the other three books on the Three Pilgrimage Festivals is widespread but by no means universal: To read them is a venerable custom among Ashkenazic Jews, but many Sephardic Jews do not associate the three books with the three festivals. The association is thus weaker also among Hasidic Jews who were influenced by Sephardic customs.
