'Nations' in the Bible

Make not yourselves unclean in any of these things; for in all these have the nations which I am casting out before you made themselves unclean.

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

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

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

But I will remember toward them the covenant with their ancestors whom I brought forth out of the land of Egypt before the eyes of the nations, that I might be their God: I am Jehovah.
