Isaiah 8.23b and the Three Great Parts of the Book of Isaiah

H.G.M. Williamson has proposed that Isa. 8.23b-9.6 inspired the relations between the first and second parts of the book of Isaiah, first with the time of the darkness and then with the time of the light. In this article Gosse demonstrates that the context of 8.23b inspired in fact the relations between the three great parts of the book. The third part underlines the difficulties of the coming of the light on the return from the exile.
