It's Esau, your firstborn son - Genesis 27:19
Jacob tried to accomplish something that God already said was his will
It went terribly wrong when he schemed and lied to make that goal a reality
He received his father's blessing but only after lying to him at least 4 times
Jacob and Rebekah decieved his father through sinful means what God had wanted to do through righteous means
They would face many consequences for his sin including Laban's deception before giving him Rachel as Jacob's wife - Genesis 29
