 The Book of Jonah is read every year, in its original Hebrew and in its entirety, on Yom Kippur – the Day of Atonement, as the Haftarah at the afternoon mincha prayer.According to Rabbi Eliezer, the fish that swallowed Jonah was created in the primordial era and the inside of its mouth was like a synagogue; the fish's eyes were like windows and a pearl inside its mouth provided further illumination.According to the Midrash, while Jonah was inside the fish, it told him that its life was nearly over because soon the Leviathan would eat them both.
