Charles Ellicott Commentary Job 2:11

"Now when Job`s three friends heard of all this evil that was come upon him, they came every one from his own place: Eliphaz the Temanite, and Bildad the Shuhite, and Zophar the Naamathite, and they made an appointment together to come to bemoan him and to comfort him." — Job 2:11 (ASV)

Eliphaz the Temanite. —Teman was the son of Eliphaz, the son of Esau, to whose family this Eliphaz probably belonged (Genesis 36:4; Genesis 36:10–11). If so, this may roughly indicate the date of the book. The inhabitants of Teman, which lay northeast of Edom, were famed for their wisdom (Jeremiah 47:7).

Bildad the Shuhite probably derived his origin from Shuah, the son of Abraham by Keturah (Genesis 25:2). Nothing is known of the district from which Zophar the Naamathite came. It probably derived its name from a Naamah or Naaman, of which there were several (e.g.,Genesis 4:22; 1 Kings 14:21; Genesis 46:21; Numbers 26:40; 2 Kings 5:1), these being names of people or of places named after them.
