John 1:32

And John bare record
The same day that he said the above things, and at the same time:

saying, I saw the Spirit;
that is, of God, as is said in ( Matthew 3:16 ) and which Nonnus here expresses; and the Ethiopic version reads, "the Holy Ghost",

descending from heaven like a dove;
at the time of his baptism; (See Gill on Matthew 3:16).

And it abode upon him;
for some time; so long as that John had a full sight of it, and so was capable of giving a perfect account of it, and bearing a certain and distinct testimony to it.
