Which ones? Those who have the Spirit of Christ as a inward born again Jew .Or an outward Jew that stands in the same place as a unconverted gentile. Without God in the present world. . dead in trespasses and sin .
I would suggest studying the meaning of …. ye are not in the flesh
Romans 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
There were some that wanted to us their DNA or picture ID to get in. They did not have the Spirit of Christ in them working to both will and do the good pleasure of our God (God is not a man he is not Jewish)
Revelation 2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Revelation 3:9 Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
What is the new name he named his wife as born again inward Jews in Acts that do have the Spirit of Christ. .. Christian?
I can now understand better why you have difficulties accepting the mystery of divine plan of redemption.
You seem to read Paul into everything that happened before Paul. Why not read the Bible literally? Here are the relevant scripture involving who Jesus was ministering to when he was in the flesh.
====
Genesis 17
10 This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
11 And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.
14 And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.
Romans 15:8
Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises
made unto the fathers:
Matthew 15:24,Matthew 10:6 both indicated Jesus was sent to the lost sheep of the house of Israel
======
So to give a direct answer to your question, Jesus was a minister to All the Jews who are yet to be cut off from Israel, meaning they are circumcised and follow the law of Moses.
They are the lost sheep, the nation have rejected God in the ot. His good news or gospel to them is very simple, “repent of that rejection and accept me as the son of God that was prophesied by your prophets. I will usher you to the promised kingdom and be your king.”
