Ahab’s wife (7)
I believe the answer is:
jezebel
'ahab's wife' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for jezebel that I've seen before include "Shameless or immoral woman" , "OT wife of Ahab" , "Ahab's wife (OT)" , "Shameless scheming woman in the Bible" , "Biblical character" .)
