The book of Enoch describes a flat, circular Earth capped by the dome of the sky. The stars are the equivalent of angels who travel from doors in the base of the dome and travel across the sky in pre-arranged routes (a couple of stars were punished for failing to go to their assigned spots). The sun and moon likewise enter the dome through doors in its base, travel across the sky, and leave through doors in the opposite side.
