Esau disobeyed God's commandments, wed outside of Israel, and didn't value his ancestry. God's providential plan excluded Esau from the line that would produce Christ. Instead, God picked the imperfect but obedient Jacob to fulfil His promise to Abraham. Years later, Jacob's mother Rebecca assisted him in tricking Isaac and giving Jacob the blessing that Isaac had intended for Esau. As a result, Isaac blessed Jacob with all he had while giving Esau nothing.
