Biblical temptress (7)
I believe the answer is:
delilah
'biblical temptress' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for delilah that I've seen before include "Tom Jones song" , "Siren" , "Dangerous temptress - Samson's girlfriend" , "She cut Samson's hair" , "Samsons mistress" .)
