Genesis 25:28

Isaac loved Esau. Isaac’s blind partiality for his first-born, irrespective of the son’s character qualifications for family leadership, brought division into the family. As a result, wrong, misery, and injustice marked relations between the brothers and their posterity for centuries. Isaac’s preference for Esau seems to have been based, in part at least, on his love for venison. The extent to which the patriarch let his love and his sense of justice and piety be controlled by his appetite is surprising and disappointing. His experience is, furthermore, a warning to us. To prefer one child above another inevitably creates jealousy, division, bitterness, and misery.
