Delia's content with a biblical character (3)
I believe the answer is:
eli
'a biblical character' is the definition.
'eli' can be an answer for 'character' (I have seen 'Religious character' mean 'eli' so perhaps 'character' could also mean 'eli'). I'm not certain of the 'a biblical' bit.
'delia's content with' is the wordplay.
'with' says the answer is hidden in the clue.
'ELI' is hidden within 'delia content'.
Can you help me to learn more?
(Other definitions for eli that I've seen before include "Old Testament priest, the prophet Samuel's teacher" , "Biblical high priest" , "Teacher of prophet Samuel" , "High priest in the Book of Samuel" , "patriarch" .)
