What Version of the Bible Did Jesus Read?

There is a scene in the Gospel of Luke where Jesus walks into a synagogue in Nazareth, stands up to read, and someone hands him the scroll of Isaiah. He finds his place and begins… "The Spirit of the Lord is upon me, because he has anointed me to bring good news to the poor," and so on. I'm sure you've read it… but there's a question here that almost nobody asks: what exactly was he holding? ... Because there was no printed and bound Bible in Jesus' time. Today we are talking about how the Hebrew Bible actually became the Hebrew Bible… and what version of that Bible Jesus would have had access to.
