Eliphaz

[He had nothing] because Eliphaz the son of Esau had pursued him to kill him at his father’s orders; he (Eliphaz) overtook him, but since he had grown up in Isaac’s lap, he held back his hand.

[2] He had six sons,[3] of whom Omar was the firstborn, and the others were Teman, Zepho, Gatam, Kenaz and finally Amalek, who was born to his concubine Timna.

The Midrash relates that when Jacob escaped from Esau and fled to his uncle Laban in Haran, Esau sent Eliphaz to pursue and kill Jacob, his uncle, who was his Rabbi also.

Jacob gave everything he had with him to Eliphaz and said, ”Take what I have, for a poor man is counted as dead."

Eliphaz was satisfied and left his uncle and rabbi poor, but still alive: (Rashi to the Book of Genesis Gen 29:11) According to Louis Ginzburg's Legends of the Jews, Eliphaz was a prophet.
