«La gloria di Yhwh risplende su di te» (Is 60,1).Is 56,9–64,11 nel libro di Isaia e centralità di Is 60,1-22

After the studies of W.H. Brownlee on the Isaiah Scroll found at Qumran (1964) and the Commentary by J.D.W. Watts (1985-87) studies on Isaiah have slowly abandoned the structure of the book in three parts, dating back to Duhm (1892): Proto-Isaiah (chaps. 1-39); Deutero-Isaiah (chaps. 40-55); Trito-Isaiah (chaps. 56-66), in favor of a different partition which sees the chaps. 1-33 on one side and the chaps. 40-66 on the other. Of particular importance is the final section of the book of Isaiah 56:9–64:11, no longer identified as the work of a third anonymous post-exilic author (Trito-Isaiah), but as a composite poem, which rereads the pre-exilic and post-exilic Isaiah prophecy in light of the situation of Jerusalem during the Persian period. The poem, work of scribes and Levites serving in the temple, is built around the center constituted by the chap. 60 (the celebration of Zion as the city of justice) with an A-B-C-A’-B’ pattern (56:9–58:14 / 59 / 60 / 61–62/63–64).
