Commento su Genesi 27:19

אנכי עשו בכרך I AM ESAU THY FIRST-BORN — I am he that brings food to you, and Esau is your first-born.

ואכלה מצידי, the letter א has a chataf kametz abbreviated kametz, underneath it as the word is in an imperative mode. We have a parallel mode in Kohelet 9,7 אכול בשמחה לחמך, “eat your food joyfully,” the letter א having an abbreviated vowel segol for the same reason. On the other hand, the word ואוכלה in ואוכלה מציד בני in verse 25 of this chapter has the vowel cholem, as it is in a future mode. Just as the word זכור in זכור ה' לדוד, ”O Lord, remember in David’s favour” is in an imperative mode, and the words זכרה לחסדי דוד, “remember the loyalty of Your servant David” in Chronicles II 6,42 are in an imperative mode, so the word אכלה here is also in the imperative mode.

אנכי עשו בכרך. "I am Esau your firstborn." Jacob meant that seeing he had purchased the birthright from Esau, he was now the legal Esau. He added: עשיתי כאשר דברת אלי, "I have done in accordance with what you have said to me," meaning that the reason you told Esau to hunt game, etc., was because you assumed that he was your firstborn.
