The Book of Jasher

The Book of Jasher (Sefer haYashar) is a non-canonical apocryphal book. It is mentioned twice in the Hebew Bible - once in Joshua 10:13: 'And the Sun stood still and the Moon stayed until the people had avenged themselves on their enemies. Is this not written in Sefer HaYashar?' and once in Samuel 1:18: 'To teach the sons of Judah [the use of] the bow. Behold it is written in the book of Jashar.' There are several separate works by this title all composed much later than Biblical times. This particular one is a translation of a Hebrew book printed in 1613. The Hebrew title of the book means 'Book of the Upright' but the title was at some point treated as a proper name - Jasher. The text of the book covers the creation of the world to the death of Moses with several minor variations to the traditional Bible.
