Actually, the KJV pretty much clearly states that he was Syrian:
And Isaac was forty years old when he took Rebekah to wife, the daughter of Bethuel the Syrian of Padanaram, the sister to Laban the Syrian.
The fact that the KJV doesn't mention divination directly isn't really too troubling. Redemption often uses
extra-Biblical sources to confirm identifiers of certain characters (i.e. Herods are Roman). As long as the sources are historically accurate and don't conflict with the truth of the Bible, they are acceptable. For this situation, we used a different translation of the Bible, which should be even more compelling for a Bible-based card game than extra-biblical sources.
