OT prefiguring of Baptism:
OT-- Baptism prefigured
I will sprinkle clean water upon you, and you shall be clean from all your uncleannesses, and from all your idols I will cleanse you.
A new heart I will give you, and a new spirit I will put within you; and I will remove from your body the heart of stone and give you a heart of flesh. I will put my spirit within you, and make you follow my statutes and be careful to observe my ordinances. Then you shall live in the land that I gave to your ancestors; and you shall be my people, and I will be your God.
Compare this to ACTS 2:37-38

While Apollos was at Corinth, Paul passed through the upper country and came to Ephesus. There he found some disciples. And he said to them, “Did you receive the Holy Spirit when you believed?” And they said, “No, we have never even heard that there is a Holy Spirit.” And he said, “Into what then were you baptized?” They said, “Into John’s baptism.” And Paul said, “John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, Jesus.” On hearing this, they were baptized in the name of the Lord Jesus. And when Paul had laid his hands upon them, the Holy Spirit came on them; and they spoke with tongues and prophesied. There were about twelve of them in all.

ROMANS 6: 3-4
Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death?
We were buried therefore with him by baptism into death, so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.
For as many of you as were baptized into Christ have put on Christ.
In him also you were circumcised with a circumcision made without hands, by putting off the body of flesh in the circumcision of Christ;
and you were buried with him in baptism, in which you were also raised with him through faith in the working of God, who raised him from the dead
one Lord, one faith, one baptism,
but when the goodness and loving kindness of God our Savior appeared, he saved us, not because of deeds done by us in righteousness, but in virtue of his own mercy, by the washing of regeneration and renewal in the Holy Spirit,
1 PETER 3:21
Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a clear conscience, through the resurrection of Jesus Christ,
