harvester

I'm a little stuck... Click here to teach me more about this clue!

'spider-woman keeps a bible' is the definition.
I can't tell whether this definition defines the answer.

'woman keeps a bible' is the wordplay.
'woman' becomes 'hester' ().
'keeps' means one lot of letters goes inside another.
'bible' becomes 'rv' (Revised Version, revision of King James Bible).
'a'+'rv'='arv'
'hester' placed around 'arv' is 'HARVESTER'.

Can you help me to learn more?

(Other definitions for harvester that I've seen before include "Reaping-machine" , "may belong to farmer" , "One gathering in crops" , "Crop gatherer" , "Long-legged spider" .)
