פירוש על בראשית 27:42

ויגד לרבקה WERE TOLD TO REBEKAH — It was told her by the Holy Spirit what Esau was thinking in his heart (Genesis Rabbah 67:9).

AND SHE SENT AND CALLED JACOB. The meaning thereof is that Jacob was in another place, not in the tent of his father and mother, since he was hiding from his brother Esau who was complaining about him, and he was ashamed or afraid of him.

עשו בנו הגדול, her elder son Esau. The reason she used the word הגדול "the bigger one," instead of הבכיר, "the older one", was because she was describing Esau's relative prowess compared to the physically smaller Jacob.
