Pound of poetry (4)
I believe the answer is:
ezra
'pound of poetry' 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 "Fifteenth book of the Old Testament" , "Old Testament book and rabbi" , "religious book" , "Old Testament prophet" , "- Pound, twentieth century US poet" .)
