Comentário sobre Gênesis 36:5

ואהליבמה ילדה וגו׳ AND OHOLIBAMAH BARE etc. — This Korah was an illegitimate child for he was the son of Eliphaz (cf. vv. 15, 16, 18) who had taken his father’s wife — Oholibamah, the wife of Esau — for he is enumerated also amongst the chiefs of Eliphaz at the end of this section (Genesis Rabbah 82:12).

את עדה בת אילון החתי, “Ada, daughter of the Hittite Eylon;” Rashi claims that Ada was identical with Bosmas, seeing the latter had acquired that nickname as she was in the habit of burning up a lot of fragrant incense to please the idol she worshipped. Nachmanides notes that Rashi failed to explain why Be-eri, the father of Oholiav who is called here Anah, is called Be-eri elsewhere. Furthermore, seeing that Bosmas was a daughter of Ishmael, this clearly was a proper name and not a nickname as we know from verse 3. On the other hand, the Bosmas who is described as the daughter of Eylon was nicknamed because of her burning incense frequently. Ibn Ezra claims that she simply was known by two names, as was her father. It is possible that the two first named women died without having had children, perhaps because they were reported of being so disrespectful to Yitzchok and Rivkah, as reported in Genesis Esau subsequently married a sister of his deceased wife whose name was Oholivamah, daughter of Anah. But the daughter of Ishmael, a sister of Nevayot, was renamed Bosmas the name of her predecessor, as her original name has a negative connotation in Hebrew [מחלת= the sickly one, or ‘the sickness.” Ed.] Esau was very fond of her as she stemmed from his own family, (1st cousin) and was not displeasing in the eyes of his father Yitzchok.

This Korach was of illegitimate birth and was fathered by Eliphaz... Re’m asks: How does Rashi know this? Perhaps there were two Korachs. He answers: Korach is not mentioned among Eliphaz’s sons but among Oholivomoh’s sons, [implying he was not publicly known as Eliphaz’s son]. Yet later, he is mentioned among the chiefs of Eliphaz. This implies he was of illegitimate birth.

ואהליבמה ילדה את יעיש, and Oholibama bore Yayish. This name is spelled יעיש but is read as if it had been spelled יעוש.
