'Kingdoms' in the Bible

Hezekiah prayed before the Lord and said, “O Lord, the God of Israel, who are enthroned above the cherubim, You are the God, You alone, of all the kingdoms of the earth. You have made heaven and earth.

Now, O Lord our God, I pray, deliver us from his hand that all the kingdoms of the earth may know that You alone, O Lord, are God.”
