It is well known that Esau hates Jacob
It is well known that hatred of Israel and antisemitism are deeply rooted among some nations, and it is considered 'beyond remedy' (Jacob is also a reference to the people of Israel, and Esau, his brother, serves as a general reference to the nations, especially the kingdom of Edom)
("Rabbi Shimon ben Yochai says: It is well known that Esau hates Jacob, but at that moment his compassion was stirred, and he kissed him with all his heart" – Yalkut Shimoni, Torah, Parashat Behaalotecha, Remez Tashkav; "Rabbi Shimon bar Yochai said: It is a law that it is well known that Esau hates Jacob, but his compassion was stirred at that moment, and he kissed him with all his heart" – Rashi on Genesis 33:4; also: "And the harlots hate Reuben, besides the hatred that Esau has for Jacob" – Agnon / Ir u-Mlo’a, 379; and: "What I am saying is, from the day the Kishinev events became public, no period passed without riots. I do not say that the wicked Esau hates blood, but his hands were red" – Agnon / Orach Nateh La-lon, 13)
