(We should note that Davies uses the term “rabbinic” in a somewhat anachronistic sense since, at the time of Paul, Judaism was still in the Second Temple period and had not yet entered the Rabbinic period. Properly speaking, Rabbinic Judaism become dominant over the period from the 2nd to the 6th centuries AD. Nevertheless, it is widely accepted that the roots of Rabbinic Judaism are to be found in the earlier Second Temple period.)
