"Ye men of Israel and your children"
"all that are afar off" =
Dan 9:7 O Lord, righteousness belongeth unto thee, but unto us confusion of faces, as at this day; to the men of Judah, and to the inhabitants of Jerusalem, and unto all Israel, that are near, and that are far off, through all the countries whither thou hast driven them, because of their trespass that they have trespassed against thee.
Acts 2 is specifically and only to Israel according to OT prophecy concerning Israel and has nothing to do with the nations/gentiles.
Israel was scattered throughout the world and they became known as Jews as it was in Esther's time.
God's nation was judged and the remnant scattered into all the world with the gospel.
They first went to the Jews and then to the non-jews.
If the Jews became Christians then they went to the people among whom they dwelt.
All those who received the gospel of Christ, regardless of their flesh, became the people of God, under one covenant, and one King.
It is they who will be gathered by Christ when He comes.
There will not be a return to the flesh divisions of the people of God.
1Pe 2:1 Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings,
1Pe 2:2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
1Pe 2:3 If so be ye have tasted that the Lord is gracious.
1Pe 2:4 To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious,
1Pe 2:5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
1Pe 2:6 Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded.
1Pe 2:7 Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner,
1Pe 2:8 And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
1Pe 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
1Pe 2:10 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
