In Greek mythology, when Achilles was a baby, it was foretold that he would die young . To prevent his death, his mother Thetis took Achilles to the River Styx, which was supposed to offer powers of invulnerability, and dipped his body into the water. But as Thetis held Achilles by the heel, he had a chatzitza and his heel was not washed over by the water of the magical river. Achilles grew up to be a man of war who survived many great battles. But one day, a poisonous arrow shot at him was lodged in his heel, killing him shortly after.
Achilles’ name can be analyzed as a combination of ἄχος (akhos) “grief” and λαός (Laos) “a people, tribe, nation, etc.” In other words, Achilles is an embodiment of the grief of the people. Achilles’ role as the hero of grief forms an ironic juxtaposition with the conventional view of Achilles as the hero of kleos (glory, usually glory in war).
Achilles stands as an interesting foil for the person of Yaakov. In Vayishlach, this weeks Torah portion we read:
25 And Yaakov was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Yaakov’s thigh was strained, as he wrestled with him. 27 And he said: ‘Let me go, for the day breaks.’ And he said: ‘I will not let you go until you bless me.’ 28 And he said to him: ‘What is your name?’ And be said: ‘Yaakov.’ 29 And he said: ‘Your name shall be called no more Yaakov, but Yisrael; for you have struggled with God and with men, and have prevailed.’ (Genesis 32:25-29)
What is Yaakov’s name? As we learn from Toldot, Yaakov was named for when he was born he was grabbing the heel of his brother Esav. Through his adolescence he seems weak compared to his hunter brother living as a tent dweller. Here, this week, he returns as a warrior having worked hard in the world for many years, confronted his father-in-law, and now wrestling this angel. Having struggled with men and God he is renamed Yisrael. Like Achilles Yisrael is the glory of his people, tribe, and nation. And interestingly he gets this name when he in injured. Esav is not his Achilles Heel as his name Yaakov might have indicated. Ultimately his Achilles Heel is he himself both his physical hip and his own character. Confronting the angel is how he can resolve his years in exile. All to often we point at other people instead of ourselves as the source of conflict in our lives. In the end when we mature we grow and accept that we are the ones that need to choose to change. What makes Yisrael great is not his being perfect or Godly, but rather his being vulnerable and human. Our collective Achilles Heel is thinking that there is any glory in war. Yisrael’s glory to be emulated is being introspective and reflective from a position of strength.
