'All the Kingdoms of the Earth' in the Bible

And Hezekiah prayed before Jehovah and said, O Jehovah, the God of Israel, who dwells between the cherubs, You are God Himself, You alone, of all the kingdoms of the earth. You have made the heavens and the earth.

And now, O, Jehovah our God, I beseech You, save us out of his hand, so that all the kingdoms of the earth may know that You are Jehovah God, and You only.
