The biblical Mikveh reference to Judaism conversion is only found in the Talmud. However, commands relevant to cleansing in the Mikveh
Jesus stated that Nicodemus should have understood what being born of water and Spirit meant. (John 3:3-10) A study of the significance of Old Testament washings shines light on what Jesus was talking about.
Nicodemus should have been familiar with an OT washing that changed the status of a stranger (Gentile) into a Jewish child of God. The bible depicts such as proselytes. In order for an individual to be “born” into the Jewish community, the stranger/Gentile had to obey the OT law of circumcision and submit to a Mikveh/Mikvah. The Old Testament Mikveh/Mikvah parallels the New Testament water baptism in the name of the Lord Jesus.
Surely, Nicodemus was aware of John the Baptist’s message and Jesus approval of water baptism as evidenced by Jesus’ presence during baptisms. As a teacher of Jewish concepts, Nicodemus should have seen water and Spirit baptism (Acts 2:38) as the antitype that brings about an actual change of status in the NT believer as a born again child of God.
As Jesus stated everyone must be born of water and Spirit. The Spiritual rebirth is needful to both SEE (comprehend) the kingdom of God as well as ENTER into it. (John 3:3-5)
The following is an article about the Jewish Mikveh (Mikvah). The Mikveh was a construct that held a sufficient amount of water to accommodate total immersion. It is considered a “womb” according to myjewishlearning.com. Consider the principles of this foreshadow of the NT water baptism.
“The water of the mikveh is designed to ritually cleanse a person from deeds of the past. The convert is considered by Jewish law to be like a newborn child. By spiritually cleansing the convert, the mikveh water prepares him or her to confront God, life, and people with a fresh spirit and new eyes--it washes away the past, leaving only the future…
In a sense, it is nothing short of the spiritual drama of death and rebirth cast onto the canvas of the convert's soul. Submerging into waters over his/her head, he/she enters into an environment in which one cannot breathe and cannot live for more than moments. It is the death of all that has gone before. As he/she emerges from the gagging waters into the clear air, he/she begins to breathe anew and live anew--as a baby struggling to be born. If we take this graphic metaphor a step further, we can sense that the mikveh is a spiritual womb. The human fetus is surrounded by water. It does not yet live. The water breaks in a split second and the child emerges into a new world. "As soon as the convert immerses and emerges he/she is a Jew in every respect… The newborn Jew takes on a Hebrew name, but a given name only is not sufficient to locate a person within the Jewish tradition. When Jews sign legal documents or are called up to the Torah, their parents' names are appended to their Hebrew names to locate them in Jewish spiritual space. A convert traditionally adopts Abraham and Sarah as spiritual parents and in legal situations is referred to as "ben Avraham Avinu," "son of our Father, Abraham," or "bat Sarah Imenu," "daughter of our Mother, Sarah.

“Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.”

If everyone who believes has been born of God, then doesn’t that rule out the possibility that the water in John 3:5 is water baptism?
