Other scholars, such as Margalioth (1964) challenged the view of multiple authorship by pointing out the remarkable unity of the book Isaiah in terms of theme, message, and vocabulary. Even certain verbal formulas unique to Isaiah, such as "the mouth of the Lord has spoken," appears in both halves of Isaiah but in no other Hebrew prophetic literature. While clear differences between the two halves of the book were evident, thematically the two halves are remarkably similar, certainly more similar to each other than to any other existing prophetic literature.
Since the late 20th century, trends in critical scholarship have focused on synchronic approaches, which advocate a whole-text reading, rather than the traditional historical-critical diachronic approaches, which tend to be directed at taking the text apart, looking for sources, redactional seams, etc. Inspired by Hebrew Bible literary criticism done by
Robert Alter, scholars have since tended to circumscribe authorship and historical-critical questions and look at the final form of the book as a literary whole, a product of the post-exilic era which is characterized by literary and thematic unity.
