From what I understand this is your explanation of John 10:16. Tell me.....why is this not a better Explanation? Book XI, Chapter 5, Paragraph 2, Lines 5,6 &7.
The two remaining tribes in Judea, under the influence of the Romans, of course would be, Judah and Benjamin and a portion of Levi. As Josephus writes.....the Ten tribes are yet beyond the Euphrates....and a number not to be estimated. Sounds to me like that pretty much accounts for most of the Lost Tribes.
The Apostles were given the commission to go to the Lost Tribes and Jesus himself says, He was sent only to the Lost Tribes and Peter also says that's exactly where he is writing from (beyond the Euphrates) and writing to another contingent of Israelites along the shores of the Black Sea. Notice these folks have a "Foreknowledge of God"....they are not just your average Gentile as most folks portray and believe them to be.
***The Apostles were given the commission to go to the Lost Tribes and Jesus himself says, He was sent only to the Lost Tribes ***
Actually it was to the LOST SHEEP OF THE HOUSE OF ISRAEL.
Go ye not in the way of the Gentiles nor enter the houses of the Samaratans, but go rather to the lost sheep of the house of Israel. (Sending forth the 70)
To the Syro-Phoniecian woman he said, "I am sent to none but ONLY the lost sheep of the house of Israel.
We must also remember that there were quite a few from the other tribes in Israel at that time such as Anna of the tribe of ASHER.
And Paul said Christ was a minister to the circumcision to confirm the promises made unto the Fathers.
Christ did not go to Northern Europe or any other place esxcept Israel.
