וַיֶּחֱרַ֨ד יִצְחָ֣ק חֲרָדָה֮ גְּדֹלָ֣ה עַד־מְאֹד֒ וַיֹּ֡אמֶר מִֽי־אֵפ֡וֹא ה֣וּא הַצָּֽד־צַיִד֩ וַיָּ֨בֵא לִ֜י וָאֹכַ֥ל מִכֹּ֛ל בְּטֶ֥רֶם תָּב֖וֹא וָאֲבָרֲכֵ֑הוּ גַּם־בָּר֖וּךְ יִהְיֶֽה׃
이삭이 심히 크게 떨며 가로되 그런즉 사냥한 고기를 내게 가져온 자가 누구냐 너 오기 전에 내가 다 먹고 그를 위하여 축복하였은즉 그가 정녕 복을 받을 것이니라

Isaac Alfasi, over the Abraham and Jacob, perhaps referring to Rabbeinu Tam.
