'Nations' in the Bible

Now if You kill these people as one man, then the nations (Gentiles) that have heard of Your fame will say,

“For from the top of the rocks I see Israel,And from the hills I look at him.Behold, the people [of Israel] shall dwell aloneAnd will not be reckoned among the nations.

“God brought Israel out of Egypt;Israel has strength like the wild ox;He will devour [Gentile] nations, his adversaries (enemies),And will crush their bones in pieces,And shatter them with his arrows.

Balaam looked at Amalek and took up his [fifth] discourse (oracle) and said:“Amalek was the first of the [neighboring] nations [to oppose the Israelites after they left Egypt],But his end shall be destruction.”
