'National' in the Bible

“‘Don’t you know what I and my fathers have done to all the peoples of the lands? Have any of the national gods of the lands been able to deliver their land from my power?

He also wrote letters to mock Yahweh, the God of Israel, saying against Him:Just like the national gods of the lands that did not deliver their people from my power, so Hezekiah’s God will not deliver His people from my power.
