Jacob and Esau were twins born to Rebekah and Isaac. Jacob used trickery to “steal” Esau’s blessing for himself. This made Jacob, not Esau, Isaac’s legal heir. To keep Jacob safe, Isaac told him to go to his uncle Laban. On the way there, Jacob had a vision, in which God promised to bless him with many descendants. Many years later, while Jacob was on his way back home, he was approached by an unknown figure (usually considered an angel or the Lord), with whom he wrestled. Afterward, the figure blessed and re-named Jacob “Israel,” for he had wrestled with God and humans, but prevailed.
