Isaac was the promised son of Abraham and Sarah, husband of Rebekah, and father of Esau and Jacob.
Biography
Isaac was born when Abraham and Sarah were advanced in age, fulfilling God's long-delayed promise of a son. Genesis 22 recounts Abraham's testing when commanded to offer Isaac, with God ultimately providing a ram in his place. Abraham's servant later obtained Rebekah as Isaac's wife. After years of barrenness, Rebekah bore twins, Esau and Jacob. Isaac lived as a pastoral patriarch in Canaan, experienced conflict over wells, and received renewed covenant promises from God. In old age he intended to bless Esau, but Jacob, aided by Rebekah, received the principal blessing through deception. Isaac later knowingly blessed Jacob before sending him to Paddan-aram.
Biblical Significance
Isaac is the second patriarch and the child through whom God's covenant promises to Abraham continued. His near-sacrifice became an enduring biblical picture of faith, provision, and the beloved son, while God's preservation of Isaac ensured continuation of the promised line.
