In favour of words found in the Old Testament (8)
I believe the answer is:
proverbs
'in the old testament' is the definition.
I can't judge whether this definition defines the answer.
'in favour of words' is the wordplay.
'in favour of' becomes 'pro' (being pro a particular cause).
'words' becomes 'verbs' (verb is a kind of word).
'pro'+'verbs'='PROVERBS'
'found' is the link.
Can you help me to learn more?
(Other definitions for proverbs that I've seen before include "Truthful expressions" , "Adages, saws" , "More than one saw" , "Old Testament book ascribed to Solomon, or well-known sayings" , "Book of the Bible" .)
