Part of the Pentateuch (7)
I believe the answer is:
numbers
'part of the pentateuch' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for numbers that I've seen before include "See 3" , "They subdue the pain" , "which may knock you out?" , "Biblical book - anaesthetics" , "Quantities; Old Testament book" .)
