If you take the old 52 card deck, and try to shuffle, and they get away from you, they will “scatter” without necessarily being “lost.”
Some of those 52 might land at your feet, while most will go flying elsewhere. The ones that land at your feet will be as scattered from the rest, as the rest are from the ones at your feet.
Some Israeli individuals and families who were kept in the land of the northern tribes by the Assyrians (maybe to keep the land tilled; maybe as slaves) were as scattered from the majority who were driven out and carried off, as the ones who were carried off were from those who were kept locally by the Assyrians.
ALL were scattered!
I believe that was called the diaspora?
