'Nations' in the Bible

I will shake all the nations; and they will come with the desirable and precious things of all nations, and I will fill this house with glory and splendor,’ says the Lord of hosts.

I will [in the distant future] overthrow the thrones of kingdoms and destroy the power of the kingdoms of the [ungodly] nations; and I will overthrow the chariots and those who ride in them, and the horses and their riders will go down, every one by the sword of his brother [annihilating one another].
