פּירוש אויף 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).

ויגד לרבקה את דברי עשו בנה, “Rivkah was informed of the words of her son Esau;” he was saying quite openly what was in his heart, i.e. that as soon as his father would die, he would murder his twin brother. Someone who had heard him say this told his mother.

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.

מתנחם לך DOTH COMFORT HIMSELF CONCERNING THEE — He regrets the brotherly relationship existing between you, harbouring thoughts other than those of brotherhood, to estrange himself from you and to kill you. The Midrashic explanation (Genesis Rabbah 67:9) is: In his eyes you are already regarded as dead and he has drunk for you (i. e. because he regards you as dead) the cup of consolation (which it was customary for near relatives of the deceased to drink). But according to the real meaning the word signifies “comforting” — he will comfort himself for the loss of the blessings by killing you.
