“The words of Esau her elder son were told to Rebecca, and she sent and summoned Jacob her younger son, and said to him: Behold, your brother Esau consoles himself [mitnaḥem] in your regard to kill you” (Genesis 27:42). “Were told to Rebecca…” – who told her? Rabbi Ḥagai in the name of Rabbi Yitzḥak: The matriarchs were prophets, and Rebecca was one of the matriarchs. Rabbi Yitzḥak said: Even a layman does not plow a furrow within a furrow, but prophets plow a furrow within a furrow?20Since a layman does not plow once and then plow a second time in a manner that destroys the first furrow, certainly the prophets do not perform an action which would be followed by an action which causes destruction.
Rebecca told Jacob to take the blessings, and this led Esau to plan to kill him. Therefore, Rebecca, who was a prophetess, had been told by God of Esau's plan, and knew that what she did would not cause destruction (Matnot Kehuna). And you say: “Do not touch My anointed ones; do not harm My prophets” (Psalms 105:15). “She sent and summoned Jacob” – she said to him: ‘This wicked one, how much he regrets about you, how much he is accepting condolences [mitnaḥem] in your regard, and he has already drunk a cup of consolation over you.’
