Is there a biblical basis for Zoroastrians worshiping a different God than the God of the Bible?

If Cyrus king of Persia practiced the Zoroastrian faith and God (presumably Jehovah) moved his heart (2 Chronicles 36:22) and Cyrus prayed to him (Ezra 1:2), what are the biblical bases that Zoroastrians worship a different god than the God of the Bible? **2 Chronicles 36:22 NIV** > In the first year of Cyrus king of Persia, in order to fulfill the > word of the Lord spoken by Jeremiah, the Lord moved the heart of Cyrus > king of Persia to make a proclamation throughout his realm and also to > put it in writing: > > “This is what Cyrus king of Persia says: > > “‘The Lord, the God of heaven, has given me all the kingdoms of the > earth and he has appointed me to build a temple for him at Jerusalem > in Judah. Any of his people among you may go up, and may the Lord > their God be with them.’” **Ezra 1:2 NIV** > “This is what Cyrus king of Persia says: > > “‘The Lord, the God of heaven, has given me all the kingdoms of the > earth and he has appointed me to build a temple for him at Jerusalem > in Judah. I am not looking for opinion, but the biblical bases for either position.
