In context
7Do not be surprised that I told you: you must be born from above. 8The wind blows where it pleases; you hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.” 9Nicodemus asked him, “How can such things be?” 10Jesus answered him, “You are the teacher of Israel, and you do not understand this? 11Very truly I tell you, we speak of what we know and testify to what we have seen, and you people do not accept our testimony.
