This interpretation of the opening of the Book of Isaiah proposes a typology of prophetic superscriptions, challenges the existence of the genre of a prophetic lawsuit, and interprets Israel's offenses against the socially vulnerable as a resistance to the just rule of JHWH with calamitous consequences. Seen in the light of Isa.1, Isaiah's speech (Isa.6) is directed against a people whose tyrannical behavior recalls that of the Egyptian Pharaoh.
