Jasher is recommended reading for history in the old testament, we are given permission to read the book of Enoch because it is referred to in the new testament, I don't believe anyone had the right to hide those books from us, the prophets knew about the book of Jasher and the Apostles obviously knew about the book of Enoch..they are not to be referred to for Salvation purposes, but for history? Yes..Is what we have the origional books? Well, pieces of Enoch are part of the dead sea scrolls, I don't know about Jasher, only God knows for sure..but Jesus did say.."as in the days of Noah....", and I believe there was more going on in those days than marrying and giving in marrage, violence and people wallowing in sin..you can bet if we're doing it now, they were doing it then..I believe The Angels that left their place brought all their technical skills with them and gave it all to mankind..IMHO and it's just my opinion, I believe Ecclesiastes means what says when it says there is nothing new under the sun..Remember, there are good reasons why these books are not the Bible. They maybe interesting or fascinating to read (I personally haven't read either one), but they should not be taken with the same weight and authority as scripture. JMHO.
