Strange realities figure in the Bible (9)
I believe the answer is:
israelite
'figure in the bible' is the definition.
The definition suggests a singular noun which matches the answer.
'strange realities' is the wordplay.
'strange' indicates anagramming the letters.
'realities' anagrammed gives 'ISRAELITE'.
(Other definitions for israelite that I've seen before include "Ancient Hebrew" , "For example, Nathanael" , "such as David?" , "Old Hebrew" , "one of the chosen?" .)
