Son born to Abraham and Sarah in fulfillment of God's promise

Isaac was the promised son born to Abraham and Sarah in their old age.  The name Isaac means “he laughs.”  Isaac’s older half-brother was Ishmael, son of Abraham and Hagar. God commanded Abraham to sacrifice Isaac, but at the last moment told him to offer a ram instead. Later, Abraham sent a servant to Haran, the place that he had left many years before, to find a wife for Isaac. The servant met Rebekah beside a well and brought her to Canaan to be Isaac’s wife. Isaac and Rebekah were the parents of twin sons: Esau the elder son, and Jacob the younger son. Isaac favored Esau but Rebekah favored Jacob. In Isaac’s old age Rebekah and Jacob tricked him into blessing Jacob, the younger son, rather than Esau, the elder son.
