The biblical canon itself does not contain a book titled Jasher. However, a “Book of Jasher” is referenced twice within the Old Testament. These mentions serve as allusions to a separate, non-canonical text that was presumably known to the original audience of the biblical narratives.
The significance of these references lies in their implication of extrabiblical sources utilized by the biblical authors. The inclusion of this text highlights the existence of a wider body of literature and traditions circulating within ancient Israel. Understanding these references allows for a more nuanced perspective on the formation and transmission of biblical texts and their relationship to contemporary cultural and literary contexts.
