'Nations' in the Bible

Israel is [as if] swallowed up [by enemies];They are now among the nationsLike a vessel [of cheap, coarse pottery] that is useless.

Yes, even though [with presents] they hire allies among the nations,Now I will gather them up;And [in a little while] they will begin to grow weak and diminishBecause of the burden imposed by the king of princes [the king of Assyria].

Ephraim was a watchman with my God, a [true] prophet [to warn the nation];But the snare of a bird catcher was laid in all his paths.And there is only deep hostility in the house of his God (the land of Israel).

My God will reject them and cast them awayBecause they did not listen to Him;And they will be wanderers (fugitives) among the nations.
