Job’s excessive plaint against his aggressive and hostile God is intertwined with his surprising confession of confidence (“Bekenntnis der Zuversicht”). It seems to be a special relationship between these two poles which are forming quasi two focuses of an ellipse. This article studies in ch. 16 (and 19) each pole and especially their interrelation in contrast to mitigating tendences in the ancient versions and the rabbinic exegesis. The mythic language of Job’s lament is compared with similar accadian literature for demonstrating both analogies and important differences. The author of the Book of Job uses especially the language of the mythic struggle against chaos (“Chaoskampf”) for his peculiar view of the dialectics in God.
