RAV KOOK ON Toldot PART 1: Harnessing the Power of Esau

We know little about the birth of most Biblical personalities. Yet, the Torah describes in detail the birth of Jacob and Esau and their respective naming. "The first one came out reddish, hairy all over like a fur coat. They named him Esau. His brother then came out, his hand grasping Esau's heel. He named him Jacob." (Gen. 25:25-26) The name Esau means 'made' or 'completed'. From day one, Esau was full of strength and energy. The name Jacob (Ya'akov) refers to the fact that he was holding on to Esau's heel (ekev). Later on, Jacob is named a second time; here too, his name refers to his relationship with his brother Esau. The night before meeting up with Esau, he struggles with a mysterious stranger. This stranger — according to some, Esau's guardian angel — informs him: "Your name will no longer be Jacob, but Israel. You have struggled with angels and men, and you have prevailed" (Gen. 32:29). What is the inner meaning of Jacob's names? What is the significance of his grasping on to Esau's heel? Why does he have two names?
