Isaac was the child of promise, the first and perhaps only child of Abraham and his wife, Sarah. It was through him that God’s promise to Abraham was passed down and fulfilled, though we are told that Abraham had other children before he died (see Genesis 25:1-2). Isaac married Rebekah and they had twin sons, Esau and Jacob. Esau, the hunter, a man of strength and good looks, was the elder and was loved by his father. Jacob, the younger, the homebody, was loved by his mother.
As Isaac neared his death, he recognized that the blessing and covenant of God must be passed to the next generation. Far greater than any earthly gift we might look for in the will of a passing family member, the blessing of God was an inheritance to be cherished, desired and protected. Because of his faith in God and His promise, Isaac made a special effort to pass this gift along to his children.
