Distribute the whole first part of the Bible (5)
I believe the answer is:
Here is my best explanation:
'distribute' is the definition.
(allotting is a kind of distributing)
'the whole first part of the bible' is the subsidiary indication.
'the whole' becomes 'all' (I've seen this in other clues).
'first' is a charade indicator (letters next to each other).
'part of the bible' becomes 'ot'.
(Other definitions for allot that I've seen before include "split up", "parcel out", "Assign or distribute", "Dedicate", "deal", "Apportion, share", "Share out", "Give as a share, or a task to be done", "Earmark" and "Grant".)
