'Nations' in the Bible

But if you destroy this people {all at once}, the nations that will have heard your message will say,

Because from the top of [the] rocks I see him, from hilltops I watch him. Behold, a people [who] dwell alone, they do not consider themselves among the nations.

God, who brings him out from Egypt, [is] like the strength of a wild ox for him. He will devour [the] nations [who are] his enemies; he will break their bones; he will pierce [them with] his arrows.

And he looked [at] Amalek, {uttered} his oracle, and said, "Amalek [is] first of [the] nations, but his future [will be] forever ruin."
