For, lo, I will command, and I will sift [the house of Israel] among [all nations],
like as corn is sifted in a sieve, yet shall not the least grain fall upon the earth”
-odd the house of Israel was sifted among [all nations here],
not the house of Judah. [Amos 9:9] When did this happen ?
I stand by my previous post and reasons, which you haven't addressed here. The leadership in the North was deported and replaced, certainly. But most of the populace remained in place to be ruled by Assyria.
"Therefore the Lord was very angry with Israel, and removed them out
of his sight: there was none left but the tribe of Judah only" (2 Kings 17:18).
And you still haven't dealt with the verses I posted. The North wasn't a viable self-governing entity anymore as they had been overtaken by Assyria, but most of the populace probably remained in place. Some of the reasons I have were previously given.
The Jewish historian Josephus (37–100 CE) wrote that "the ten tribes are beyond the
Euphrates till now, and are an immense multitude and not to be estimated in numbers".
Well, then Josephus overstates his case here.
