>>8867599And just to answer your question OP, Esau, his older brother sold his birthright for a bowl of porridge. He disregarded his precious birthright as nothing to be traded over a single meal his brother had made, there should be an emphasis at that. And since Jacob had the birthright, it wouldn't have been totally wrong or weird for him to inherit the blessings, even though Issac woulnd't have given it to him if he knew what was going on. There is a lot of truth packed in Genesis, and many stories in Genesis are written in an allegotically, and that's what we should look for aside from the history. The younger overtaking and outperforming the older and being persecuted is a constant theme in the bible. It happened with the story of Cain & Abel, Hagar & Sarah, with Ishmael & Israel, Esau & Jacob, Epharaim & Menasseh, Jacob's children and Joseph, Saul & David, and so on. They paint a clear picture of the OT & NT/ history of the "jews" with Jesus Christ at midpoint/ this world and the next world. Also the animal covering represents being counted righteous for your faith in Jesus, whereas Esau represents one's own works (he literally goes out to hunt for meat on his own). We can't get saved on our own, we need the finished work of Jesus Christ. People have this misconception that Old Testament and the New Testament is unrelated, but everything in the old testament points to Jesus Christ, especially in Genesis. Adam and Eve making apron out of fig trees also reprent work salvation, which doesn't work. Instead, God gives them a clothing out of animal skin (animals had to be sacrificed for that) which also points to Jesus Christ and his death, burial, and resurrection for the remission of our sins. Here's an good sermon if you are interested but I really recommend hearing the full gospel first then delving into the King James bible.
