In the LDS Pearl of Great Price, Moses Chapters 6-7, produced by Joseph Smith in December of 1830, we have significantly more information about Enoch than is found in the Bible or was elsewhere available to Joseph Smith.  Later Enoch literature, 2 Enoch, 3 Enoch and the Book of Giants, found in the Dead Sea Scrolls in 1948, demonstrate Joseph Smith got right an unusual name, key story-line points and other details unavailable to him.  This is significant evidence Moses 6-7 is an inspired document.
