People in the Bible destroying Satan with holiness (13)
I believe the answer is:
thessalonians
'people in the bible' is the definition.
The definition suggests a singular noun which matches the answer.
'destroying satan with holiness' is the wordplay.
'destroying' indicates anagramming the letters.
'with' is a charade indicator (letters next to each other).
'satan' put after 'holiness' is 'holinesssatan'.
'holinesssatan' with letters rearranged gives 'THESSALONIANS'.
Can you help me to learn more?
(Other definitions for thessalonians that I've seen before include "two biblical books" , "Old people" .)
