Jacob, the man of the tent

Jacob was left alone, and a man (ish) wrestled with him until the rise of dawn (Genesis 32:25). Who was this unknown assailant Jacob was struggling with? Many commentators identify him as angel. An alternative approach to the identity of the mysterious antagonist is Jacob was wresting with himself. In Genesis 30:43 Jacob is clearly referred to as ish, man. The “man of the tent” has come a long way. Preparing to meet his brother, Jacob looks at his financial success and begins to worry. He quickly separates all that he owns and all that he loves into different camps. Left completely alone, he must face his demons. Has the fulfillment of the stolen blessings actually turned him into Esau? Did the accumulation of physical wealth compromise his spirituality with God?
