'Nations' in the Bible

"'Don't defile yourselves in any of these things: for in all these the nations which I am casting out before you were defiled.

"'As for your male and your female slaves, whom you may have; of the nations that are around you, from them you may buy male and female slaves.

I will scatter you among the nations, and I will draw out the sword after you: and your land will be a desolation, and your cities shall be a waste.

You will perish among the nations, and the land of your enemies will eat you up.

but I will for their sake remember the covenant of their ancestors, whom I brought forth out of the land of Egypt in the sight of the nations, that I might be their God. I am Yahweh.'"
