Prayer books were kept in valuable covers, such as velvet or leather, and in richer families, they were often bound in silver. The silver binding embellished with thick acanthus leaves on brown velvet base was made in the middle of the 19th century and serves as a cover for a Sephardic prayer book used at pilgrimage festivals. ls. The three Pilgrimage Festivals are the holidays of Passover (Pesach), Shavuot, and Sukkot. The reason for calling them pilgrimage derives from the Temple period, when the people of Israel made pilgrimage to Jerusalem on these festivals, in order to celebrate the holiday together in the Temple of Jerusalem as prescribed in the Torah.
