John 1:33-35

33 I myself did not know who he was, but the one who sent me to immerse in water said to me, ‘The one on whom you see the Spirit descending and remaining, this is the one who immerses in the Ruach HaKodesh.’

34 And I have seen and borne witness that this is the Son of God.”

35 The next day, Yochanan was again standing with two of his talmidim.
