According to "God delivered the King of the Jews, Ahaz, into the hands of the King of Syria, who carried away a great multitude of them captives to Damascus. And he was also delivered into the hand of the King of Israel, who smote him with a great slaughter".In the prophet says clearly that a prerequisite for the fulfillment of the prophecy is that Ahaz stands firm in his faith. This means that he should trust God and not seek military help in the Assyrians which Ahaz nevertheless did.
