Lalu Abraham mengangkat matanya dan melihat, dan tampaklah kemudian seekor domba jantan yang tanduknya tersangkut di semak belukar. Maka Abraham pergi, mengambil domba jantan itu, lalu mempersembahkannya sebagai korban bakaran sebagai pengganti anaknya.
Rashi
והנה איל BEHOLD, A RAM — It was predestined for that purpose from the six days of Creation (Avot 5:5; Midrash Tanchuma, Vayera 23).
Bekhor Shor
And he saw; and behold, a ram: And he nevertheless would not have taken it, as he was afraid lest another person lost it; and he would not extend his hand [to take the property] of others. But "after it was caught in the thicket by its horns," he knew that it was a sign to him that he should take it and that it was stuck there for his sake. So he went and took it.
Chizkuni
אחר נאחז בסבך, “subsequently he saw a ram that had become entangled in the thicket.” We find a similar construction (using the preposition אחר) in Psalms 68,26: קדמו שרים אחר נוגנים, “the singers preceded the musicians,” or in Kohelet 12,2: ושבו העבים אחר הגשם, “and the clouds return after the rain.”According to Rashi, Avraham saw the ram as it became entangled. This is why he understood that it was not there accidentally, but that G-d had given him a hint to use it as a substitute for the offering he had been prevented by the angel to complete. If that ram had been standing there as did others, he would have thought it was privately owned by someone else and would not have touched it. A different interpretation: “he noticed it after it had become entangled by its horns.” (Ibn Ezra).
