The next day John saw Jesus coming to him and said, Look! There is the Lamb of God, Who takes away the sin of the world! [Exod. 12:3; Isa. 53:7.]
This is He of Whom I said, After me comes a Man Who has priority over me [Who takes rank above me] because He was before me and existed before I did.
And I did not know Him and did not recognize Him [myself]; but it is in order that He should be made manifest and be revealed to Israel [be brought out where we can see Him] that I came baptizing in (with) water.
John gave further evidence, saying, I have seen the Spirit descending as a dove out of heaven, and it dwelt on Him [never to depart].
And I did not know Him nor recognize Him, but He Who sent me to baptize in (with) water said to me, Upon Him Whom you shall see the Spirit descend and remain, that One is He Who baptizes with the Holy Spirit.
And I have seen [that happen–I actually did see it] and my testimony is that this is the Son of God!
