>all the tribes are not mentioned. Dan and Ephraim are missing. Hmmmmm..
This fact is sometimes used to suggest the ENTIRE tribe of Dan left, along with parts of the tribes of Asher and Judah, when that group escaped by sea, several hundred years before the overland Exodus. I don't buy that as there are other citations which suggest that Danites were present in Assyria with the others, during that beginning of Northern Kingdoms diaspora.
Friend, I've been reading your posts and looked at your profile. There are no lost tribes. Even if there were some "lost tribes" it wouldn't make any difference. The true Israel of God is the New Testament Church, His Bride. Scripture speaks nothing of any "lost tribes" being found. Either you are in Christ or not. If not, you are not His.
