Genesis 36:4

And Adah bare to Esau Eliphaz
This son of Esau, according to Jerom ^F14, is the same with him mentioned in the book of Job, as one of his friends that came to visit him, ( Job 2:11 ) ; and so says the Targum of Jonathan on ( Genesis 36:10 ) ; but he rather was the grandson of this man, since he is called the Temanite: and Bashemath bare Reuel;
the name is the same with Reuel or Raguel, the name of Jethro; but cannot be the same person as is said by some, for he was a Midianite and not an Edomite, ( Exodus 2:18 ) ( Numbers 10:29 ) .
