2:30 But King Sihon of Heshbon was unwilling to allow us to pass near him because the Lord our God had made him obstinate and stubborn so that he might deliver him over to you this very day.
Isaiah 6:10
6:10 Make the hearts of these people calloused;
make their ears deaf and their eyes blind!
Otherwise they might see with their eyes and hear with their ears,
their hearts might understand and they might repent and be healed.”
