'Kingdoms' in the Bible

Of [all] the kingdoms it will be [the most] lowly, and it will not exalt itself again over the nations, and I will make them small [so as] not to rule over the nations.

And I will make them into one nation in the land on the mountains of Israel, and {they will all have one king as their king}, and they will not again be two nations and will not again divide into two kingdoms again.
