The Three Pilgrimage Festivals, known as the Shlosha Regalim (שלושה רגלים), are three major festivals in Judaism — Pesach (Passover), Shavuot (Weeks), and Sukkot (Tents or Booths) — when the Israelites living in ancient Israel and Judea would make a pilgrimage to Jerusalem, as commanded by the Torah. In Jerusalem, they would participate in festivities and ritual worship in conjunction with the services of the kohanim ("priests") at the Temple in Jerusalem.
