John 3:5-7

King James Version

⁵ Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.

⁶ That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.

⁷ Marvel not that I said unto thee, Ye must be born again.
