Peopel take this and isolate it:
Mat 15:24, “And He answering, said, “I was not sent except to the lost sheep of the house of Yisra’yl.”
A shown earlier those in the Messiah are grafted in Israylites no matter of Hebrew/Jew or Gentile.
Shown here:
Romans 9:6-8, "However, it is not as though YHWH's plan had failed. For it is not everyone who is a descendant of Yisra’yl who belongs to Yisra’yl. Nor, just because they are his descendants, are they all Abraham's children; but: In Isaac will your seed be called. That is, it is not those who are the children of the flesh who are YHWH's children; but it is the children of the promise who are regarded as Abraham's seed."
Exodus 12:47-49, “All the congregation of Israel shall keep it. And when a stranger shall sojourn with thee, and will keep the Passover to יהוה, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof. One law shall be to him that is nativeborn, and unto the stranger that sojourns among you.”
So only for Israyl is true because anyone that follows Him is Israyl.
Peopl also take this:
Matthew 10:5, "יהושע sent these twelve out, having commanded them, saying, “Do not go into the way of the nations, and do not enter a city of the Shomeronim,"6, "but rather go to the lost sheep of the house of Yisra’ĕl."7, "“And as you go, proclaim, saying, ‘The reign of the heavens has drawn near.’
"Do not go into the way of the nations" and isolate it, but as I said it seems that Yahshua/Jesus was building up a base of people that could carry His doctrine on after He ascended, because after His resurrection He said this:
Mat 28:19-20,28:19, “Therefore, go and make disciples of all the nations, immersing them in the Name of the Father and of the Son and of the Set-apart Spirit, and make disciples of all the nations, immersing them in the Name of the Father and of the Son and of the Set-apart Spirit. Teaching them to observe all things that I have commanded you. And lo, I am with you always, to the end of the age.”
“nations” is word #G1484 - ethnos: a race, a nation, pl. the nations (as distinct from Isr.), Original Word: ἔθνος, ους, τό, Part of Speech: Noun, Neuter, Transliteration: ethnos, Phonetic Spelling: (eth'-nos), Short Definition: a race, people, the Gentiles, Definition: a race, people, nation; the nations, heathen world, Gentiles.
Also worth saying that His words will never pass away:
Mat 24:35, “Heaven and earth may pass away, but My teachings will not pass away.”
John/Yahanan 5:39, “You search the Scriptures, because you think you possess everlasting life in them. And these are the ones that bear witness of Me.”
John/Yahanan 14:26, “But the Comforter; the Holy Spirit which YHWH will send in My Name will teach you all things, and bring all things to your remembrance, whatever I (Yahshua/Jesus) have said to you.”
John/Yahanan 6:63, “It is the Spirit that gives life; the flesh is useless. The words (Instructions) that I (Yahshua/Jesus) speak to you, they are Spirit, and they are life everlasting.”
John 14:23-24, “יהושע answered him, “If anyone loves Me, he shall guard My Word. And My Father shall love him, and We shall come to him and make Our home with him. He who does not love Me does not guard My Words. And the Word which you hear is not Mine but of the Father Who sent Me.”
now there are many false doctrines too many to talk about all ofthem, but there is somethign called "replacement theology" this is also false, the now "God hates Jews and only Gentiles are good" this is just as false as the "only Jews thing"
Being in Messiah is the important thing, don't ever let anyone tell you die\fferent or steer you away from His words.
1 John 3:24, “And the one guarding His commands stays in Him, and He in him. And by this we know that He stays in us, by the Spirit which He gave us.”
John 13:35, “By this shall all know that you are My taught ones, if you have love for one another.”
John/Yahanan 14:6, "Yahshua proclaimed to him: I am the way, the truth, and the life; no man comes to the Father, except through Me."
John/Yahanan 10:16, "And I have other sheep that are not of this fold. I must bring them also, and they will listen to My voice. So there will be one flock, one Shepherd (4166 –poimén)."
