'Nations' in the Bible

Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out from before you;

And as for thy bondmen, and thy bondmaids, whom thou shalt have; of the nations that are round about you, of them shall ye buy bondmen and bondmaids.

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

And ye shall perish among the nations, and the land of your enemies shall eat you up.

but I will for their sakes 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 Jehovah.
