Likutei Sichos vol. 35 page 76-81. After all is said and done and Avrohom shows infinite loyalty to Hashem, he begins protesting. In this Sichha the Rebbe shows (in Rashi’s view at least), that Avrohom was never questioning God, but the fact that maybe Hashem thought he was somehow unworthy of giving of himself to…

Likutei Sichos vol. 01 page 31-4. Sara (the Zohar says) is the body and Avrohom is the Soul, yet, Avrohom 1) listens to her 2) mourns for her, as she is the purpose.

Likutei Sichos vol. 15 page 145 ff. After Sara passes away we see her life. Her life is about the Jewish people exclusively, while Avrohom is about all of humanity. This shows itself in each of the big events in this Parsha.

Likutei Sichos vol. 15 page 122 ff. Torah Ohr Toldos (beg.)

Likutei Sichos vol. 15 page 191 ff. Avrohom looked so much closer to Yishmael. In fact Yishmael did Teshuva during his father’s lifetime, while Aisav seemed so evil.

Likutei Sichos vol. 20 108 ff. Aisav is Yitzchok’s son and as he is in Yitzchok, he and Yaakov are just two versions of avodas Hashem, one that is like a Chossid and the other one who overcomes his Yetzer HaRa. Aisav just made bad choices.

Likutei Sichos vol. 01 page 63 ff. Vol. 3 page 787 ff. Yaakov was the most successful of the Avos, as all his children were Tzadikim and he had them in Golus.

Likutei Sichos vol. 15 page 243 ff. Ya’akov makes two conditions with Hashem and then two promises. This Sicha shows that the requests were for help at serving Hashem to set up the fulfillment of the two promises. Aliyas HaNeshama and Dira BiTachtonim.
