Pound of literature (4)
I believe the answer is:
ezra
'pound of literature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ezra that I've seen before include "High priest" , "Eponymous OT priest" , "Old Testament book and rabbi" , "... Pound, American poet who lived in Italy" , "Book after II Chronicles" .)
