More good points? LOL You've been saying all along that Hebrew would've been preserved and then nanrod said Hebrew would not have been preserved in captivity and you say "good point"? You can't remember what you're saying.
The whole idea was to assimilate the conquered, not send them off on a funny new career.
So you think it was some kind of desegregated busing? LOL Put an Israelite house between two Assyrian houses? You're funny.
If you stay in big groups and don't have to deal that much with a dominant culture, you keep your language. If you're forced into small groups and thus have to deal with the dominant culture on an individual personal basis, you better learn the lingo. Your kids will learn it better than you will at any rate.
What doesn't happen in any event is the appearance of a really new language out of this situation. And from what Indoeuropean conquerors did the Hebrews acquire their "Celtic" or whatever language?
