Kabbalah do Rodzaju 27:15

"And Rivkah took the best clothes of her eldest son Esau" (Beresheet 27:15). These are the garments Esau took from Nimrod. They are the precious garments from Adam, which came to the hands of Nimrod, who used them when he hunted, as it is written, "He was a mighty hunter before Hashem" (Beresheet 10:9). And Esau went into the field, where he fought with and killed Nimrod, removing the garments from him. This is the meaning of "and Esau came from the field, and he was faint" (Beresheet 25:29). It has already been explained why it is here written, "And he was faint," and elsewhere, "for my soul faints before the slayers" (Yirmeyah 4:31). These are analogous. There it is written "faint" to refer to killing. Here too, there is killing, because Esau murdered Nimrod.
