Hebrew patriarch losing head about awful one, a prophet (7)
I believe the answer is:
obadiah
'prophet' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for obadiah that I've seen before include "Hebrew prophet" , "piece from Hebrew Bible" , "Old Testament book and prophet" , "OT prophet" , "Single-chapter OT book" .)
