You’re evidently the one that doesn’t understand. You keep avoiding the essence of my question and are unable to show the passage which states that the Lost Sheep are actually Gentiles……this in direct conflict with your Savior’s own words to His disciples!
Tell us all…….when did Yeshua change His mind? Don’t you think that something as earth shattering as that would deserve a word or two in scripture?
I gave you all pertinent scriptures but you don't want to do your homework.
I ask you rather a question : Show me in NT that God has made a New Covenant with other than two houses of Israel. There lies your query about those Gentiles. If you are not able to see translators' folly of using unnecessary word 'Gentiles' as being Abraham's promised children (as he is the physical father of many nations) then you don't understand the gospel message.
Gen 17:
6 And I will make thee exceeding fruitful, and I
will make nations of thee, and kings shall come out of thee.
Yahuah promises Abraham He will make nations of him (his descendants). Abraham, though he didn't live to see the promise fulfilled but he believed in the promise and because of this he was accounted to be righteous.
Same promise was made to Jabob/Israel:
Gen 35:
10 God said to him, “Your name is Jacob. Your name will no longer be called Jacob, but your name will be Israel.” So he called his name Israel.
11 And God said to him, “I am El Shaddai.
Be fruitful and multiply. A nation and a company of nations will come from you, and kings will come from your body.
These are the same people (nations) are called 'Gentiles' in the NT. The translators have confused the people in Christendom to think 'Gentiles'are purely of heathen people. Well, they are not!
The confusion in Christendom is that they believe Israel to be only Jews (who comprised of only 2 tribes). Yes during Messiah's ministry and The Apostles Jews were the only ones who kept their ethnicity and represented Israel. The rest of the tribes were dispersed into various countries.
KJV translated other tribes of Israel (non-Jews) as Gentiles:
Mat 4:
15 The land of Zabulon, and the land of Nephthalim,
by the way of the sea, beyond Jordan,
Galilee of the Gentiles;
Zabulon, Nephtali were tribes of Israel. Galilee was also land allotted to some tribes of Israel.
There you can understand how Gentiles was applied to the non-Jewish tribes of Israel.
By the grace of God, I understand the true gos.pel. It's you who needs to understand the true gospel which must connect to Abraham and his Seed Messiah.
