I have read the claim that Jesus set the OT canon in Luke 11:47-51 when Jesus was speaking about the murders of Abel to Zacharias. The argument is that only books written between these two time periods could possibly be included in the OT. There are a few that come after the murder of Zacharias, but the argument goes that they were contemporaneous to Zacharias, so Zacharias would have condemned them prior to his murder, so those books and prophets must count.
How do I respond to this argument? The several hundred references in the NT to the Deuterocanonical books does not seem to be a good enough argument here.
thanks for your help.
