'Nations' in the Bible

Alas [for] those being at ease in Zion, and those who feel secure on Mount Samaria, the notables of the best of the nations! The house of Israel resorts to them.

"Yes, look, I [am] going to command and I will shake the house of Israel among all the nations like one who shakes with a sieve, but not a pebble will fall [to the] ground.

Thus they may take possession of the remnant of Edom and all the nations {who are called by my name}," {declares} Yahweh, [who] does this.
