בראשית, פרק ל״ו, פסוק ג׳

Esau's decision to marry within his extended family brings to light a complex web of relationships and the ancient practice of name changing. The historical record presents his new wife as Basemath, the daughter of Ishmael, yet earlier accounts identify her as Mahalath. The primary approach among commentators is that she simply went by two names. This was a highly common occurrence in the ancient Near East, where individuals frequently held multiple names or adapted them to fit changing life circumstances [אם למקרא, גור אריה]. Alternatively, the two names might be linguistically linked. In Aramaic, the root of Mahalath means sweet, which mirrors the Hebrew meaning of Basemath, a name denoting sweetness and the pleasant scent of perfume [שד״ל].

Taking a different view, some suggest that neither were her original birth names, but rather descriptive titles [רמב״ן]. According to this perspective, Esau actively changed her name from Mahalath, which in Hebrew carries an unfortunate resemblance to words for illness and ugliness, to the much more dignified Basemath. Esau held a special affection for her. Because she was part of the family, she did not cause grief to his parents, Isaac and Rebekah. This stood in sharp contrast to his previous wives, who were punished and died without bearing sons [רמב״ן, ביאור שטיינזלץ].

The name Mahalath also serves as the foundation for a profound teaching regarding forgiveness. There is a tradition that three types of people receive a clean slate and have all their past wrongs forgiven: a convert, a person elevated to a position of leadership, and someone entering into marriage [רש״י, רבנו בחיי]. This total forgiveness stems from the idea that marriage transforms an individual into a completely new and whole creation, whereas a person without a spouse is viewed as merely half a body [גור אריה, חומש קה״ת]. Furthermore, marriage represents the deep acceptance of responsibility. Just as a convert takes responsibility for their new path and a leader takes responsibility for their generation, a person stepping into marriage accepts the responsibility of guiding a home [פרדס יוסף]. Remarkably, even though Esau was known for his wickedness and already had wives and children, the very act of this marriage granted him forgiveness at that exact moment [משכיל לדוד]. However, there is an interesting dispute regarding exactly who received this fresh start; while some maintain it was Esau whose sins were wiped clean, others argue the name Mahalath indicates that it was actually the bride's sins that were forgiven [שד״ל, ברכת אשר על התורה].

The family record also carefully notes that she was the sister of Nebaioth. This detail reveals a tragic timing: her father, Ishmael, passed away shortly before the wedding. Consequently, her brother Nebaioth stepped up to take responsibility, arranging the marriage and giving her away to Esau, which is why she is closely associated with his name [רש״י]. Beyond the family tragedy, the specific mention of Nebaioth serves a crucial purpose. It proves beyond any doubt that this woman is the exact same person mentioned previously, firmly dispelling any thought that Ishmael might have had two different daughters who married Esau [ברכת אשר על התורה].
