This is the first attempt systematically to explain the growth, background and ideology of the Targum to Isaiah. Its principal stages of development between the first and fourth centuries CE are described in order to understand as precisely as possible its hope for God''s messianic vindication of his people. Chilton''s work demonstrates the paradigmatic significance of the Isaiah Targum within the Prophets Targum as a whole, and convincingly places the Targum in its chronological and theological context.
