I have done a little research on the Dead Sea Scrolls and I have a question concerning when they were written. Most all experts claim the scrolls found were written from between 250-100 BC. However a few say they could have been written as late as 70 AD. To me this is critical. If they were written (copied) around 100 BC, then we have the entire book of Isaiah copied for us before Jesus was even born. We specificaly have Isaiah 53 copied 100 years plus before He was born. I use this in apologetics to encourage believers in understanding fulfilled prophecy. So it is important I have it right. My question is "is it set in stone that these scrolls are from 100 BC?"
