Take Esau, for example. Genesis 36:5 tells us, "Oholivama bore Yeush, and Yalam, and Koraḥ; these are the sons of Esau, who were born to him in the land of Canaan." Seems straightforward. But the rabbis of the Midrash, specifically in Bereshit Rabbah, see something much deeper at play here.

The verse "Oholivama bore…" immediately triggers a question: "How has Esau been searched?" (Obadiah 1:6). Rabbi Simon uses a striking image to explain why the Torah delves into Esau's lineage. He compares it to peeling an onion. Just as you peel away layer after layer of an onion to get to its core, the Torah meticulously lists Esau's genealogy to reveal hidden truths. Yefeh To’ar, a commentary on Bereshit Rabbah, explains that the Torah lists the genealogical records of Esau to reveal their secrets.

But why go to such lengths? The verse from Jeremiah (49:10) offers a clue: "I have exposed his hidden places." The goal, according to the Midrash, is to expose the mamzerim among them. Now, mamzer is a Hebrew term for someone born from a forbidden union, carrying significant social and legal implications.

So, how many mamzerim are we talking about? Opinions vary. Rav says three. Rashi, the great medieval commentator, suggests these are Ana, Oholivama herself, and Timna. Or, as Yefeh To’ar suggests, maybe the three sons of Oholivama mentioned in the verse. Rabbi Levi, however, ups the ante to four, including the Koraḥ mentioned in our verse, or perhaps Timna, depending on how you interpret the earlier sources.

And then Rabbi Binyamin, quoting Rabbi Levi, drops a bombshell: the Koraḥ mentioned here was a mamzer. Talk about family drama! The text tells us that Koraḥ is listed both as a son of Esau's wife Oholivama (Genesis 36:5) and as a son of Esau's son Elifaz (Genesis 36:16). Rashi explains that this implies Koraḥ was the illegitimate child of Oholivama and Elifaz. A scandal worthy of a soap opera, right there in the Torah!

What does all this mean? Why this deep dive into Esau’s family secrets? Perhaps it's a reminder that the Torah isn't just a collection of stories, but a complex tapestry woven with layers of meaning. It suggests that even in seemingly mundane details, there are profound truths waiting to be uncovered. It serves as a cautionary tale, perhaps, about the consequences of choices and the enduring impact they have on generations to come. And maybe, just maybe, it reminds us that no family is perfect, and that even within the imperfections, there are lessons to be learned.
