'Nations' in the Bible

Israel has come to destruction; now they are among the nations like a cup in which there is no pleasure.

But though they give money to the nations for help, still I will send them in all directions; and in a short time they will be without a king and rulers.

Have no joy, O Israel, and do not be glad like the nations; for you have been untrue to your God; your desire has been for the loose woman's reward on every grain-floor.

My God will give them up because they did not give ear to him; they will be wandering among the nations.
