In this paper we describe our research project on dating the language of the Book of Jeremiah using a combination of traditional biblical scholarship and machine learning. Jeremiah is a book with a long history of composing and editing, and the historical background of many of the sections in the book are unclear. Moreover, redaction criticism and historical linguistics are mostly separate fields within the discipline of Biblical Studies. With our approach we want to integrate these areas of research and make new strides in uncovering the compositional history of Book of Jeremiah.
