Give out everything with books (5)
I believe the answer is:
allot
'give out' is the definition.
(I've seen this before)
'everything with books' is the wordplay.
'everything' becomes 'all' (all things).
'with' says to put letters next to each other.
'books' becomes 'OT' (abbreviation for Old Testament).
'all'+'ot'='ALLOT'
(Other definitions for allot that I've seen before include "Give, apportion" , "Allocate" , "Assign or distribute" , "Dish out" , "Dispense or distribute" .)
