I am listening to The Case for Christ on Audible right now, which I very highly recommend. In one of his interviews, Lee Strobel goes into Jesus’ reply to John’s disciples in Matthew 11 and points out that his “the dead are raised” part isn’t a quote from Isaiah 35 or 61 because it’s just not there. But it is to be seen in a Dead Sea scroll which leading papyrologists date to around 30 B.C. Jesus wasn’t just quoting the Nevi’im. Among other things, this provides authenticity, as though any where needed, that Matthew 11, which we’ve had for almost two millenia before uncovering this Dead Sea scroll, records the very words of Jesus.
