Book of Jasher — the “Book of the Upright” or “Book of the Just Man,” a lost non‑canonical text referenced in the Hebrew Bible and tied to biblical history.
Also called the Book of the Upright or Just Man, the Book of Jasher is a paradoxically famous yet missing work cited in Joshua and Samuel and treated by scholars as apocryphal/pseudepigraphal or parabiblical literature. This PDF explores its historical references, traditions about medieval manuscripts and translations, theological implications, and scholarly debates around authenticity and usage in biblical studies. Includes context on John Martin’s 1816 painting and relevance for readers of faith and researchers in ancient Jewish literature.
