Jacob wrestles with a mysterious being in Parashat Vayishlach and is renamed Yisrael.
Parashat Vayishlah presents the climax in Jacob’s journey from a trickster youth who gets his way through deception to a mature adult who faces life’s challenges with integrity. He is about to confront his estranged brother Esau for the first time in 20 years. He fears for his life as he believes Esau is still angry over being cheated out of his birthright. The night before meeting Esau, Jacob encounters a mysterious being on the banks of the Jabbok and they wrestle all night. Towards dawn, Jacob prevails but the sparring partner strikes him in his hip and causes permanent injury. Jacob emerges triumphant but wounded. He is renamed Yisrael- the one who wrestles with God and man and prevails. Later (33:18), Jacob is described as “Shalem,” whole or at peace. Even though Jacob is hurt in a wrestling bout, he is a much more whole person for finding within him the integrity to repair his relationship with his brother.
