Biblical name in every thesaurus (4)
I believe the answer is:
esau
'biblical name' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'biblical' relates to this answer.
'in every thesaurus' is the wordplay.
'in' says the answer is hidden in the clue.
'ESAU' is hidden in the letters of 'every thesaurus'.
Can you help me to learn more?
(Other definitions for esau that I've seen before include "Isaac's eldest son" , "wronged brother" , "Son of Isaac and Rebecca" , "man tricked by kid brother" , "He traded his birthright for a mess of pottage" .)
