He took on the Seed of Abraham !
Did Adam represent all mankind in the beginning ? No he did not, for he only represented the seed of Abraham which was the only seed in the beginning before sin. Adam represented a Godly Seed
Mal 2:15
And did not he make one [Adam and Eve]? Yet had he the residue of the spirit.
And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
This is the Seed of Abraham through whom Christ would come. Now lets look at Christ's genealogy from Luke 3 and we find that Abraham is in that generation which began with Adam
Lk 3:3-38
23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,

38 Which was the son of Enos, which was the son of Seth,
which was the son of Adam, which was the son of God.
If we start back at Gen 5, there the record begins as to who were of
the generations Adam and it ends at the end of Chapter 5:1-32
Quote:
This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;
2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.
3 And Adam lived an hundred and thirty years, and begat a son in his own likeness, and after his image; and called his name Seth:
4 And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:
5 And all the days that Adam lived were nine hundred and thirty years: and he died.
6 And Seth lived an hundred and five years, and begat Enos:
7 And Seth lived after he begat Enos eight hundred and seven years, and begat sons and daughters:
8 And all the days of Seth were nine hundred and twelve years: and he died.
9 And Enos lived ninety years, and begat Cainan:
10 And Enos lived after he begat Cainan eight hundred and fifteen years, and begat sons and daughters:
11 And all the days of Enos were nine hundred and five years: and he died.
12 And Cainan lived seventy years and begat Mahalaleel:
13 And Cainan lived after he begat Mahalaleel eight hundred and forty years, and begat sons and daughters:
14 And all the days of Cainan were nine hundred and ten years: and he died.
15 And Mahalaleel lived sixty and five years, and begat Jared:
16 And Mahalaleel lived after he begat Jared eight hundred and thirty years, and begat sons and daughters:
17 And all the days of Mahalaleel were eight hundred ninety and five years: and he died.
18 And Jared lived an hundred sixty and two years, and he begat Enoch:
19 And Jared lived after he begat Enoch eight hundred years, and begat sons and daughters:
20 And all the days of Jared were nine hundred sixty and two years: and he died.
21 And Enoch lived sixty and five years, and begat Methuselah:
22 And Enoch walked with God after he begat Methuselah three hundred years, and begat sons and daughters:
23 And all the days of Enoch were three hundred sixty and five years:
24 And Enoch walked with God: and he was not; for God took him.
25 And Methuselah lived an hundred eighty and seven years, and begat Lamech.
26 And Methuselah lived after he begat Lamech seven hundred eighty and two years, and begat sons and daughters:
27 And all the days of Methuselah were nine hundred sixty and nine years: and he died.
28 And Lamech lived an hundred eighty and two years, and begat a son:
29 And he called his name Noah, saying, This same shall comfort us concerning our work and toil of our hands, because of the ground which the Lord hath cursed.
30 And Lamech lived after he begat Noah five hundred ninety and five years, and begat sons and daughters:
31 And all the days of Lamech were seven hundred seventy and seven years: and he died.
32 And Noah was five hundred years old: and Noah begat Shem, Ham, and Japheth.
It ends with Noah. It picks back up with shem in
Gen 10:21
21 Unto
Shem also, the father of all the children of Eber, the brother of Japheth the elder, even to him were children born.
Cp
Luke 3:36,
34
36 Which was the son of Cainan, which was the son of Arphaxad, which was the son of Sem, which was the son of Noe, which was the son of Lamech,
And Vs 34 we have Abraham
34 Which was the son of Jacob, which was the son of Isaac, which was the son of Abraham, which was the son of Thara, which was the son of Nachor,
Out of Noah's sons in the generation of Christ only shem is mentioned leading back to Adam !
So understand, Christ did not merely take on human nature n general for all mankind, but He took on a specific and particular segment of mankind, a remnant if you will, the Seed of Abraham, So
Heb 2:16
16 For verily he took not on him the nature of angels;
but he took on him the seed of Abraham.
The ESV For surely it is not angels that he helps, but
he helps the offspring of Abraham.
You see that ? Jesus Christ came to seek and to save and to help the offspring of Abraham, not all men without exception !
The Aramaic bible brings it good:
For death was not authorized over the Angels,
but death was authorized over the seed of Abraham.
Which means Christ's was only Authorized to come and aid a particular seed within mankind !
No other segment did He Identify with. When speaking on to whom Salvation came in Lk 19, notice His words carefully
Lk 19:8-10
And Zacchaeus stood, and said unto the Lord: Behold, Lord, the half of my goods I give to the poor; and if I have taken any thing from any man by false accusation, I restore him fourfold.
9 And Jesus said unto him,
This day is salvation come to this house, forsomuch as he also is a son of Abraham.
10 For the Son of man
is come to seek and to save that which was lost.
This mis that which Christ came to seek and to save which was Lost in Adam, the Seed of Abraham, a Chosen People separate from all other peoples of the Earth ! Adam in the beginning was the Natural and Federal Head of that People ! Thats God's World by the way !
