Sefer haYashar

Sefer haYashar is a reference to the Five Books of Moses, Joshua 10:13, see Targum Jonathan, "sifra d'oriaitho"; named on behalf of the Patriarchs who were call "Yesharim", see Numbers 23:10. Sefer haYashar (Hebrew ספר הישר) means "Book of the Upright One", but Jashar is generally left untranslated into English and so Sefer haYashar is often rendered as Book of Jasher.
