Yes, Rózsa used for the choruses Babylonian/Yemenite/Hebrew sources, but these „Preghieras“ sound somehow different as the others in the movie. Especially track 21 & 22 with the strange accompaniment of the drum. I have no idea, where they had to be used in the film. And the yiddish „Danza“ sounds to modern, it seems to belong rather in FIDDLER ON THE ROOF than a ancient story.
When you have listened to them, William, you will understand.
