Biblical book, or endless ditty performed by a single monk? (4,2,7)
I believe the answer is:
song of solomon
'biblical book' is the definition.
'song of solomon' can be an answer for 'book' (I've seen this before). I'm unsure of the 'biblical' bit.
'endless ditty performed by a single monk?' is the wordplay.
I cannot quite understand how this works, but
'ditty' could be 'song' (I've seen this before) and 'song' is present in the answer.
'single' could be 'solo' (I've seen this before) and 'solo' is found within the answer.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Another definition for song of solomon that I've seen is " Old Testament book".)
