Some Pharisees emerge (5)
I believe the answer is:
arise
'emerge' is the definition.
(I've seen this before)
'some pharisees' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ARISE' is hidden in the letters of 'pharisees'.
(Other definitions for arise that I've seen before include "Ascend" , "Get up or come up" , "Spring - get up" , "Become apparent" , "Originate; stand up" .)
