Brennan Breed’s “The Reception History of Isaiah: Unsealing the Book” takes a single theme attested in just a few verses (Isa 8:16; 29:11; and 30:8) and shows how it has been reinterpreted by readers ceaselessly across the centuries, all the way from later biblical authors to modern times, in response to everything from sectarian divisions to African-American slavery to the trauma of the Holocaust. These verses refer to the words of the prophet being sealed, especially to those who are ignorant, until the time comes for their meaning to be revealed. This theme brings into focus the ways in which Isaiah has been used polemically, and it also points to the text’s power as a seemingly inexhaustible well of meaning.
