“Is not this written in the Book of Jasher?"
Joshua 10:13
“Behold it is written in the Book of Jasher."
II Samuel 1:18
The Bible has a few books in the Old Testament mentioning books that were considered lost, among them is the Book of Jasher. This particular extracanonical book was originally written and printed in Hebrew in 1552, and later in Venice in 1625.
Sephir Ha Yasher, the Hebrew title, means the “Book of the Just Man”, or “the Upright Record”. This text covers much of the same terrain as the Mosaic books of the Bible, from the creation to the death of Moses, with some minor differences.
