In this book, Aaron Hornkohl defends the diachronic approach to Biblical Hebrew and the linguistic dating of biblical texts. Applying these methodologies to the biblical book of Jeremiah, he dates the work on the basis of its linguistic profile, determining that, though composite, Jeremiah is likely a product of the transitional time between the First and Second Temple Periods. Hornkohl also contributes to unraveling Jeremiah's complicated literary development, arguing on the basis of language that its 'short edition', as reflected in the book's Old Greek translation, predates that 'supplementary material' preserved in the Masoretic edition but unparalleled in the Greek. Nevertheless, he concludes that neither is written in Late Biblical Hebrew proper.
