Берешит 25:26 Комментарий: Tze'enah Ure'enah, Rashi, Chizkuni & Da'at Zekenim

“Isaac was sixty years old when they were born” [25:26]. Isaac was sixty years old when Jacob and Esau were born. Rashi asks a question. Why did Isaac wait for twenty years and prayed after twenty years. One prays after ten years when one’s wife does not have children. The explanation is that Isaac first waited until Rebecca was thirteen years old when she could have children. From thirteen years, he waited another ten years, as is the custom to wait when a woman has no children and then one prays.²¹Rashi, Genesis, 25:26.

ואחרי כן יצא אחיו וגו AND AFTERWARDS HIS BROTHER CAME OUT, ETC. — I have heard a homiletical midrash that expounds it according to its simple meaning: It was with justice that he was grabbing him to hold him back. Jacob was conceived from the first drop and Esau from the second. Go and learn from a tube with a narrow opening - put in it two stones, one after the other. The one that goes in first will come out last, and the one that goes in last will come out first. It comes out that Esau, who was conceived last, came out first, and Jacob, who was conceived first, came out last. And [so] Jacob came to hold him back, so that the first for birth would be the same as the first for conception; and he would open [his mother's] womb and take the first-born status with justice (see Genesis Rabbah 63:8).

וידו אוחזת, “with his hand grabbing;” the younger baby’s had is portrayed as holding on to the older twin’s heel already while still inside Rivkah’s womb. The author cites as proof for this Hoseah 12,4: בבטן עקב את אחיו, “in the womb he tried to overtake his brother.” The word עקב is understood to mean: “heel, hoof.” Yaakov is presumed to have tried to prevent Esau from becoming the firstborn. He wanted to become the firstborn as he had developed from his father’s first drop of semen as quoted by Rabbi Yossi’s response to the lady’s question in Pessikta Zutrata. This would enable Yaakov to claim the status of being the legal firstborn. His failure to prevent Esau from emerging from Rivkah’s womb first, prompted him years later to acquire that status through buying the birthright from his brother.
