Answer: Eliphaz

Job's three friends were Eliphaz the Temanite, Bildad the Shuhite and Zophar the Naamathite.

“Now when Job’s three friends—Eliphaz the Temanite, Bildad the Shuhite, and Zophar the Naamathite—heard about all this adversity that had come upon him, each of them came from his home, and they met together to go and sympathize with Job and comfort him.”— Job 2:11 (BSB)
