Re: “Don’t Believe Anything I Tell You”. I beg of you to please research more in depth the difference between Israel and Judah. They are not yet united.
I believe the faithful remnant of the so-called 10 lost tribes were assimilated into the southern Kingdom after the death of King Solomon (2 Chron. 11:16-17) and the Israel of today represents all the tribes.
Ezekiel 39:28 says the re-gathering of Jews through out the world will take place following the Battle of Ezekiel 38-39 which I place just before the 70th Week begins.
Rev. 7:4-8 lists every tribe except Dan among the 144,000 witnesses early in the 70th Week.
The majority of Jewish scholars believe the 12 tribes will all be represented in Israel at the beginning of the Kingdom Age (Millennium) citing Ezekiel 37:19-28 and Ezekiel 48:1-29.
But nothing in Scripture requires the official reuniting of all 12 tribes as a precondition to the End Times. In fact Jesus mentioned only those in Judea in His warning to flee when they see the Abomination of Desolation (Matt. 24:15-16) which takes place in the middle of the 70th Week.
