John 1:32-34 King James Version (KJV)
32 And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.
33 And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.
34 And I saw, and bare record that this is the Son of God.
John 1:32-34 Amplified Bible, Classic Edition (AMPC)
32 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].
33 And I did not know Him nor recognize Him, but He Who sent me to baptize [a]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.
34 And I have seen [that happen—I actually did see it] and my testimony is that this is the Son of God!
