Ancient Hebrew realities distorted (9)
I believe the answer is:
israelite
'ancient hebrew' is the definition.
(I've seen this before)
'realities distorted' is the wordplay.
'distorted' indicates an anagram.
'realities' with letters rearranged gives 'ISRAELITE'.
(Other definitions for israelite that I've seen before include "Old Hebrew" , "For example, Nathanael" , "such as David?" , "Tribesman" , "Ancient Hebrew" .)
