None of the examples in the Bible specify how much water was used nor how it was applied.
You said, you accept ALL of HIS word, I for sure am not sharing my opinion but HIS word only.
As you can see, the ESV wording is different then the KJV.
Matthew 3:13-17
English Standard Version
16 And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him,[a] and he saw the Spirit of God descending like a dove and coming to rest on him;
17 and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.”
Matthew 3:16-17
King James Version
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:
17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
There HAS to be an answer!!
When it says, when JESUS was baptized, WENT UP STRIGHTWAY OUT OF THE WATER, do you think he did that represents being sprinkled or poured on?
There also HAS to be an anwer for why JESUS's disciples baptized in JESUS name.
HIS disciples KNEW who HE was.
John 14,
King James Version
9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?
10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
How about this one, JESUS speaking and HE is alos in HEAVEN.
John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
