Mixing up Torah and Bible creates a bewildering situation (6,4)
I believe the answer is:
rabbit hole
'a bewildering situation' is the definition.
(as in going down a rabbit hole)
'mixing up torah and bible' is the wordplay.
'mixing up' is an anagram indicator.
'and' says to put letters next to each other.
'torah' after 'bible' is 'bibletorah'.
'bibletorah' with letters rearranged gives 'RABBIT-HOLE'.
'creates' acts as a link.
(Other definitions for rabbit hole that I've seen before include "14 [NEST]" , "Entrance to warren" , "some places visited by Alice" .)
