Someone asked me about the scroll Jesus read in Luke 4:17-21. Is it the Dead Sea Scrolls or LXX? 

 and the scroll of the prophet Isaiah was given to him. He unrolled the scroll and found the place where it was written:

18 “The Spirit of the Lord is upon me,
    because he has anointed me
        to bring good news to the poor.
He has sent me to proclaim release to the captives
    and recovery of sight to the blind,
        to let the oppressed go free,
19 to proclaim the year of the Lord’s favor.”

20 And he rolled up the scroll, gave it back to the attendant, and sat down. The eyes of all in the synagogue were fixed on him. 21 Then he began to say to them, “Today this scripture has been fulfilled in your hearing.”

This was my answer:

It would have been a scroll containing the book of Isaiah in Hebrew.  It is not LXX because it was in Hebrew and it is not DSS because it was in Galilee not in Judean desert, BUT it would be VERY SIMILAR to the kind of Isaiah scrolls that were found in DSS/Qumran. Of course some Hebrew pro-LXX materials was found among DDS. It would be a synagogue scroll. This also is probably a literary summary citation since two passages are noted.
