Little is known of Rav's personal life. That he was rich seems probable; for he appears to have occupied himself for a time with commerce and afterward with agriculture. He is referred to as the son of noblemen, but it is not clear if this is an affectionate term or a true description of his status. Rashi does tell us that he is being described as the son of great men. He was highly respected by the Gentiles as well as by the Jews of Babylonia, as shown by the friendship which existed between him and the last Parthian king, Artaban. He was deeply affected by the death of Artaban (226) and the downfall of the Arsacid dynasty, and does not appear to have sought the friendship of Ardeshir, founder of the Sassanian dynasty, although Samuel of Nehardea probably did so.
