He appears in the Scriptures (4)
I believe the answer is:
esau
'he appears in the scriptures' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for esau that I've seen before include "Elder of the twin sons of Isaac and Rebecca" , "Biblical brother to Jacob" , "Biblical character who sold birthright for pottage" , "Son of Isaac, brother to Jacob (Bible)" , "Old Testament character sounds as if he had a vision" .)
