[16] And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him:

Mark 1:9-11 KJV
[9] And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan. [10] And straightway coming up out of the water, he saw the heavens opened, and the Spirit like a dove descending upon him: [11] And there came a voice from heaven, saying, Thou art my beloved Son, in whom I am well pleased.

John 3:23-24 KJV
[23] And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized. [24] For John was not yet cast into prison.

Acts 8:35-40 KJV
[35] Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus. [36] And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? [37] And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. [38] And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. [39] And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing. [40] But Philip was found at Azotus: and passing through he preached in all the cities, till he came to Caesarea.

Romans 6:1-4 KJV
[1] What shall we say then? Shall we continue in sin, that grace may abound? [2] God forbid. How shall we, that are dead to sin, live any longer therein? [3] Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? [4] Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.

Romans 6 uses the analogy of baptism with death.

The symbolism of being buried with Jesus by baptism into death.

As Christ was raised from his grave, so we are raised up in baptism to live a new life by following the teachings of Jesus.

NOTE: Biblical immersion baptism precludes baby or infant baptism.
