Genesis 25-36 recounts the story of Isaac's descendants, highlighting the lives of Jacob and Esau. Esau trades his birthright to Jacob, and Jacob, aided by his mother, deceives Isaac to claim Esau's blessing. Jacob flees to avoid Esau's wrath and ends up marrying Leah and Rachel, fathering twelve sons and a daughter. Jacob wrestles with a divine being and is renamed Israel, signifying his covenant with God. He reconciles with Esau after years of separation, and the narrative sets the stage for the tribes of Israel to emerge. Themes of faith, struggle, and redemption weave throughout this segment.
