Isaiah 30-31

Those that trust in Egypt will be made ashamed. At some point, God will be compassionate and will smite Israel's enemies and they will cast out all their idols.

On one hand, it is actually quite easy to read passages like that and see how the Pharisees were expecting a political-military Messiah. Likewise, the passage connects political-military deliverance with the casting out of idols. Although deliverance comes before casting out the idols in the passage, the connection could easily be made that if they as a society threw out their idols, then the political-military Messiah would come.
