'Kingdoms' in the Bible

Hezekiah prayed before Yahweh, and said, "Yahweh, the God of Israel, who sit [above] the cherubim, you are the God, even you alone, of all the kingdoms of the earth. You have made heaven and earth.

Now therefore, Yahweh our God, save us, I beg you, out of his hand, that all the kingdoms of the earth may know that you, Yahweh, are God alone."
