Name hidden in "thesaurus" (4)

I believe the answer is:

esau

(Other definitions for esau that I've seen before include "Hairy OT character" , "Son of Isaac, brother to Jacob (Bible)" , "Hairy brother to Jacob in Bible" , "Jacob's brother (OT)" , "Brother to Jacob (OT)" .)

I've seen this clue in the USA Today and the Universal.
