King in 1 Kings (4)
I believe the answer is:
ahab
'king in 1 kings' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ahab that I've seen before include "Captain hunting Moby Dick" , "Jezebel's husband or captain in 'Moby Dick'" , "Jezebel's husband - Moby Dick's hunter" , "Whaling Captain" , "Captain in search of Moby Dick" .)
