On the 1st Pentecost in 31 AD, Peter was inspired to convict all the peoples there 'devout men, from every nation under heaven' which obviously would have included Jews, Greeks, and other Gentiles.
His central message of Acts 2 is found in verses 38-41 as follows: "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. 39 For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call."
The records do not say but they most likely would be Jews.

BIBLIA ( beeblleeaa)
Most of the Bible was written in Hebrew, so your question is a little bit hard to answer. Some people say that the New Testament is written in Greek, others say Aramaic, but I am sure the whole Bible wasn't originally written in Greek, but mostly Hebrew.
It is forbidden for Jews (Deuteronomy 14:15).
The Bible makes it implicit that anyone who serves God will have a share in the future Reward.
The word "Bible" is from the Greek "Biblos", which means "Book" in English. The Latin word for "Book" is "Liber".Incidentally, this is where the word "Library" comes from. When Mohammed received his revelation, he referred to "The people of the Book", meaning Jews, Christians, and Muslims, because all three religions use and believe in the Bible. Jews use the Torah, or Old Testament; Christians use the Torah and New Testament, and Muslims use the Torah, New Testament, and Koran.
The phrase "Christ in you" occurrs only one time in the KJV bible. (Col 1:27) "To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:"
It means that while the Jews were in the desert, God took the holy bible, the Torah, So when God went to the Jewish people, the Jews answered, "Of course we want your holy Torah!" That's what it means to say that the Jews are God's chosen people!
