John 3:13 WBT

¹¹  Verily, verily, I say to thee, We speak what we know, and testify what we have seen; and ye receive not our testimony.

¹²  If I have told you earthly things, and ye believe not, how will ye believe if I tell you heavenly things?

¹³  And no man hath ascended to heaven, but he that came down from heaven, [even] the Son of man who is in heaven.

¹⁴  And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:

¹⁵  That whoever believeth in him should not perish, but have eternal life.
