What is the connection between the end of Parshat Vayishlach, which speaks about the lineage of Esav, and Parshat Vayeishev, which describes the difficult incident of Yosef and his brothers? Rashi explains that although Esav’s background is mentioned briefly, the Torah focuses on the story of Yaakov and the twelve tribes. It is compared to a precious stone that fell beneath the sand. After finding the stone, the debris is discarded and attention is focused solely on the stone. Similarly, Hashemsifted through all the generations until He found Yaakov, the bechir h’avot (the chosen one), and then focused on him.
Rashi tells another parable about a coal dealer who came to the market to sell his coal. After his arrival, another merchant arrived laden with straw. The coal dealer worried that there would not be any room now for his coal. A wise person said one spark released from your coal will decimate the entire wagonload of straw. When Yaakov saw all the generals of Esav, he worried how he would overcome them. Therefore, the Torah says, “Eleh toldot Yaakov, Yosef.” These are the children of Yaakov,Yosef. Sefer Ovadaya states, “Vayaha beit Yaakov aish u’beit Yosef l’hava u’beit Esav l’kash. (Yaakov is the fire, Yosef is the flame, and Esav is the straw.) One spark of Yosef can destroy the entire camp of Esav. The Netivot Shalom notes that Esav represents our negative inclinations. Hashem said, “V’haya beit Yaakov l’aish, your passion, desire, and yearning to do the will of Hashem will outweigh all the evil of Edom.
Rabbi Tatz explains that straw symbolizes the nations of the world who believe that the more material a person has the better off he is. Esav said, “I have a lot,” while Yaakov said, “I have everything.” What really counts is spirituality. Life is not about having, but about appreciating what one does have and elevating it for Hashem. Although Esav’s lineage seems impressive compared to Yaakov, Yaakov is central in the narrative of the Chumash.
