NO MAN in the Old Testament ever had the Holy Spirit dwelling IN them. They all had the Spirit "overshadow" them, just like Mary whom the Spirit "overshadowed" her and she was "found with child."
Although a lamb was slain BEFORE God created heaven, earth, and man, no one, as Jesus says, had the Holy Spirit dwelling within them.
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
John 14:16–17.
The Holy Spirit is necessary for salvation, for conversion. Jesus says "Even the Spirit of Truth whom THE WORLD CANNOT RECEIVE" makes an astounding statement that the world cannot be saved because they cannot receive Him (the Spirit.)
Here the world is that part of humanity Hostile toward God
7. the world, and everything that belongs to it, appears as that which is hostile to God, i.e. lost in sin, wholly at odds w. anything divine, ruined and depraved

Gentiles had received the Spirit here.
Acts 10:34–48 (KJV 1900) — 34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons: 35 But in every nation he that feareth him, and worketh righteousness, is accepted with him. 36 The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all

37 That word, I say, ye know, which was published throughout all Judaea, and began from Galilee, after the baptism which John preached; 38 How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him. 39 And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: 40 Him God raised up the third day, and shewed him openly; 41 Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. 42 And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead. 43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins. 44
While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. 45
And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. 46 For they heard them speak with tongues, and magnify God. Then answered Peter, 47
Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? 48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
