There are about a thousand opinions and one truth. Martin Trench has a decent video on the ten tribes on You Tube. There used to be an excellent one that connected ancient Samaria with my family tree, but it was removed.
THE POINT, God says He has saved himself, 7000 men. So, God has saved a branch of Israel for His Glories sake nit because of anything they did. The number 12 = Fulness, the numbers 10 and 7 always = Completeness. When god TIMES anything by 10 or 100 or 1000 it always means He is emphasizing COMPLETENESS or FULLNESS. For instance, the 144,000 are not 144,000 men else God would have to precisely choose a certainty number, that is not in God's nature. 12 (FULNESS) x 12 x 10 (COMPLETENESS) x 10 x 10 = 144,000 or ALL Israel who repent. A day is like 1000 years unto God simple means God is telling us He is ETERNAL, not a 1000 years, one day is like Eternity to God, here is why, God loves on ALL TIME at once, He lives in the beginning and the end, He is the Alpha and Omega. The 10 Horns and Toes are not 10, they simply mean ALL Europe at any given time, be it 1 Rome be it 5 nations, or be it 27 as ot was with England or 26 now. God stated they will be DIVIDED, unto after Israel is reborn, try as they might the 1 could never reunite, even by the SEED of Men (Royal Marriage). In Rev. 2:10 it states that Smyrna would have Tribulation for 10 days, well that means for the complete Church Age, not 10 days. We have the 10 Commandments that stand in fr all God's Laws etc. etc.
We have 7 Eyes and 7 Spirits in Revelation, which simply means God SEES ALL and God is EVERYWHERE, or Omnipotent.
The point is God didn't say he was going to regather Israel as a Nation, then go find the lost tribes. Go read it, it says SPECIFICALLY that God regathers the WHOLE HOUSE OF Israel when he brings them out of all the nations. WATCH:
Ezekiel 37:10 So I prophesied as he commanded me, and the breath came into them, and they lived, and stood up upon their feet, an exceeding great army. 11 Then he said unto me, Son of man, these bones are the whole house of Israel: behold, they say, Our bones are dried, and our hope is lost: we are cut off for our parts.
12 Therefore prophesy and say unto them, Thus saith the Lord God; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel.
Now, who does God gather from all the Nations according to God Himself? The WHOLE HOSE of Israel !! Not just Judah.
The problem is Satan is a SNEAKY LIAR....Thou shalt not surely die !!
