Commentaire sur La Genèse 36:2

עדה בת אילון ADAH THE DAUGHTER OF ELON — She is identical with Basemath daughter of Elon (cf. 26:34) and she was called Basemath because she offered spices (בשמים) as incense to idols.

ADAH THE DAUGHTER OF ELON. She is identical with Basmath the daughter of Elon,²⁴¹Above, 26:34. and she was called Basmath because she burned incense (besamim) to the idols. And Oholibamah, (mentioned here), is identical with Judith.²⁴¹Above, 26:34. In order to deceive his father, the wicked Esau changed her name to Judith (Jewess) to suggest that she had abandoned idol-worship.

עשו לקח את נשיו מבנות כנען, people who read the text carefully cannot help noting that when Esau’s wives’ names are mentioned for the first time in 26,34 they were referred to as יהודית בת בארי החתי and בשמת בת אלון החתי, as well as מחלת בת ישמעאל. In our paragraph no one by the name of בת בארי is mentioned at all, neither the woman’s name nor her father’s name. However אלון as well as ישמעאל the fathers of two of Esau’s wives have been mentioned here also. The names of the daughters have been inverted as happens in many instances. בשמת daughter of אלון is here referred to as עדה בת אלון whereas. It is therefore reasonable to assume that יהודית בת בארי died childless, whereas the other two wives of Esau bore children for him as is enumerated here. Esau took אהליבמה בת ענה בת צבעון החוי as a wife after his move to Seir, when he wanted to strengthen his political ties with the local inhabitants through intermarriage with them. This is why the Torah gave such a detailed account of Oholivamah’s genealogy. Timnah, concubine of Eliphaz, Esau’s firstborn, was also from the original inhabitants of the region of Mount Seir, The reasom why she is mentioned ast, is that the marriage of Esau to Oholivamah occurred last. Chronologically, she belonged to an earlier generation.
