The Ushpizin are the seven mystical visitors whom we welcome to our succot throughout the holiday, They are Abraham, Isaac, Jacob, Joseph, Moses, Aaron and David. Abraham visits on the first night, Isaac on the second, and so on.
Ushpizin comes from the Aramaic word, ushpiz, meaning a guest and also a lodging place or an inn. In modern Hebrew, the related word ishpuz means hospitalisation.
