Komentarz do Rodzaju 27:34

כשמוע...גם אני, “I am also your son, no less than he is.” The letter א in the word אני has the vowel kametz, although it does not signify a comma or something similar, as it is intended to stress the word “I.” We find a similar construction in 31,52 אם אני לא אעבור אליך, where we also would not have expected the kametz instead of the vowel patach. There too, the kametz is used to provide emphasis on the word “I.” Another example of the use of the kametz in the word אני as a means of emphasizing the speaker is Psalms 89,28 אף-אני בכור אתנהו, “I will appoint him firstborn.”

Have you not saved a blessing for me. Eisov understood that he could not receive the same blessing that his brother had received, but he was hoping for a similar one.
