ידעתי כי מקנה רב לכם – I KNOW THAT YOU HAVE MUCH LIVESTOCK – And you need this place which is grazing land. And since it is grazing land, it is called Ashterot Karnayim (Bereshit 14:5), like “the ewes (ashterot) of your livestock” (Devarim 7:13) for it was between two big and tall mountains to the extent that the sun was unable to shine in the valley that was between the two mountains due to the great depth of the valley and the height of the mountains. And in the days of summer they would have the livestock enter there because of the sun, and therefore it was called Ashterot Karnayim (“Lamb Horns”): Ashterot [ewes] named after the sheep, and Karnayim [horns] named after the heights of the mountains. And this is proven in Sukkah (Bavli Sukkah 2a:9): that the sun does not {shine} between those two mountains, for they said: “But if so, one who makes his Sukkah in Ashterot Karnayim, a place where the sun does not shine, it is not a fit sukkah.”
