'Nations' in the Bible

" 'You must not make yourself unclean in any of these [things], because the nations whom I am driving out from your presence were made unclean by all of these.

So I said to you, "You yourselves shall take possession of their land, and I myself shall give it to you to possess it--a land flowing with milk and honey"; I [am] Yahweh your God, who {has set you apart} from the nations.

And you shall be holy for me, because I, Yahweh, [am] holy, and I have singled you out from the nations to be mine.

" 'As for your slave and your slave woman who are yours, from the nations that [are] all around you, from them you may buy a slave or a slave woman.

And I will scatter you among the nations, and I will draw a sword behind you; and your land shall be a desolation, and your cities shall be a ruin.

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

And I will remember [the] first covenant for them--whom I brought out from the land of Egypt {in the sight of} the nations {to be their God}. I [am] Yahweh.'"
