And there's still the same LIE by those deceived by the false Jews, trying to DUMP God's prophecies in His Word of what He would do with the TEN LOST TRIBES OF ISRAEL UNDER EPHRAIM, that Ephraim would become "a multitude of nations"!
"Israel" below is put for Jacob, his new name God gave him...
Gen 48:14-20
14 And Israel stretched out his right hand, and laid it upon Ephraim's head, who was the younger, and his left hand upon Manasseh's head, guiding his hands wittingly; for Manasseh was the firstborn.
15 And he blessed Joseph, and said, "God, before whom my fathers Abraham and Isaac did walk, the God which fed me all my life long unto this day,
16 The Angel which redeemed me from all evil, bless the lads; and let my name be named on them, and the name of my fathers Abraham and Isaac; and let them grow into a multitude in the midst of the earth."
The above blessing is specifically to the SEED of Ephraim and Manasseh, Joseph's two sons born to him in Egypt. Jacob thus puts his name ISRAEL upon the two lads.
17 And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father's hand, to remove it from Ephraim's head unto Manasseh's head.
18 And Joseph said unto his father, "Not so, my father: for this is the firstborn; put thy right hand upon his head."
19 And his father refused, and said, "I know it, my son, I know it: he also shall become a people, and he also shall be great: but truly his younger brother shall be greater than he, and his seed shall become a multitude of nations.
20 And he blessed them that day, saying, "In thee shall Israel bless, saying, God make thee as Ephraim and as Manasseh": and he set Ephraim before Manasseh.
KJV
That above does NOT... say Ephraim would become the Gentile peoples. It declares that Ephraim's SEED would become "a multitude of nations", and that points directly to the ten scattered tribes of the northern "kingdom of Israel" becoming a great number of SEED in the new lands where God scattered them to (the "wilderness" per the Hosea 2 prophecy, which historically would be Asia Minor, Europe and the Americas).
Thus those who claim the ten scattered tribes are now NO MORE, or have literally become GENTILES, don't have a clue about this PROPHECY DIRECTLY FROM GOD THROUGH HIS SERVANT JACOB. Those deceived listening to the FALSE JEWS of the "synagogue of Satan" have simply been taught to claim the ten tribes of Israel are no more for the same reason they had Lord Jesus Christ murdered, to try and usurp Christ's Kingdom of Israel.
The liars don't realize that if the TEN SCATTERED TRIBES no longer existed after God scattered them to the "wilderness", then the Gentile would have NEVER had The New Covenant Gospel preached to them! That because The Gospel of Jesus Christ was part of the heritage contained in God's Birthright given to Joseph's two sons Ephraim and Manasseh! The Gospel of Jesus Christ is included in God's Birthrigh, first preached to Abraham, then to Isaac, then to Jacob, then to Joseph, and then to Joseph's two sons Ephraim and Manasseh.
The Gospel then... went to the Gentiles also which the TEN TRIBES UNDER EPHRAIM were scattered among. Those scattered ten tribes among the Gentiles ACCEPTED THE GOSPEL and were the main carriers of The Gospel after Christ's disciples. That's why many of Christ's Apostles preached The Gospel in Asia Minor and Europe, to preach to the ten tribes and to the Gentiles. This is why Jesus said in Acts 9 that He chose Apostle Paul to also preach The Gospel to "kings"! Figure that out brethren, because there were no kings of Israel existing in the holy land in Apostle Paul's day; Herod was of Idumean birth, not even born of Israel. A king line existed in old Spain, where Paul said he wanted to visit the brethren at. And those were the Milesian royal lineage that migrated to old Ireland and married there anointed next to the Jacob's Pillar Stone (Stone of Scone), thus starting the ancient king line of Ireland. That line continued to the ancient kings of Scotland, and then to the kings of England, all anointed on the Jacob's Pillar Stone that now resides in today's Scotland until king Charles today.
So by saying the LIE that the ten tribes of Israel and the Gentiles all became one in The Gospel means God's Prophecies specifically given to and about the TEN TRIBES and EPHRAIM AND MANASSEH did not happen is to CALL GOD HIMSELF A LIAR. And that is why those deceived who claim that don't realize their LIES come from the false Jews of the "synagogue of Satan"!
Thus the idea that the SEED of ISRAEL, like Ephraim's and Manasseh' seed, STOP being the SEED of ISRAEL by becoming a Christian is to DENY CHRIST JESUS Who is KING of ISRAEL. It is like saying GOD's ISRAEL is no more! and no longer exists! Only someone deceived and that has very little Bible knowledge would make such a false claim that God's Israel is no more because of Christ's Church! Those reveal they are TOTALLY IGNORANT of what God has said in His Word about His Israel...
The following prophecy from God IS PART OF THE GOSPLE OF JESUS CHRIST to the seed of Israel, and that means the 'seed' of Israel that BELIEVE ON JESUS CHRIST:
Jeremiah 33:20-26
20 Thus saith the LORD; If ye can break My covenant of the day, and My covenant of the night, and that there should not be day and night in their season;
21 Then may also My covenant be broken with David My servant, that he should not have a son to reign upon his throne; and with the Levites the priests, My ministers.
22 As the host of heaven cannot be numbered, neither the sand of the sea measured: so will I multiply the seed of David My servant, and the Levites that minister unto Me.
23 Moreover the word of the LORD came to Jeremiah, saying,
24 Considerest thou not what this people have spoken, saying, "The two families which the LORD hath chosen, he hath even cast them off?" thus they have despised My people, that they should be no more a nation before them.
That above in red is exactly what the jackals claim here on this forum about the ten lost tribes of Israel no longer existing as a people today. They "despised My people" God says there about them, which they are still doing to this day.
25 Thus saith the LORD; If My covenant be not with day and night, and if I have not appointed the ordinances of heaven and earth;
26 Then will I cast away the seed of Jacob, and David My servant, so that I will not take any of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and have mercy on them.
KJV
Those "two families" God mentions above in verse 24 He is pointing to the "two nations" of the Ezekiel 37 prophecy, the two sticks, the ten tribe "house of Israel" under Joseph's son Ephraim with the scattered ten tribes, and the 3-tribe "house of Judah" (Jews). Thus GOD'S ISRAEL TODAY IS STILL "TWO NATIONS", OR "TWO FAMILIES", or TWO HOUSES if you prefer. One is the JEWS of the "house of Judah" (3 tribes), and the other is the "house of Israel" (ten tribes).
So if anyone comes up to you claiming that God's ISRAEL today is only JEWS, then you know they are espousing LIES directly from the false Jews of the "synagogue of Satan" who had Lord Jesus murdered. The ten lost tribes of Israel did NOT become a Gentile seed by believing on Jesus Christ, as God has shown in several of His Old Testament prophets, the above Jeremiah 33 Scripture being just one of them.
