Collection of Biblical characters (3,3)
I believe the answer is:
job lot
This clue is a double definition.
'collection' is the first definition.
(job lot is a kind of collection)
'biblical characters' is the second definition.
(I've seen this before)
'of' acts as a link.
(Other definitions for job lot that I've seen before include "Miscellany of sale items" , "biblical characters" , "Collection of miscellaneous articles bought together" , "Collection under the hammer" , "Items bought as one" .)
