11 Truly, truly, I say to you, ^zwe speak of what we know, and bear witness to what we have seen, but ^zyou¹ do not receive our testimony. 12 If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? 13 ^aNo one has ^bascended into heaven except ^che who descended from heaven, the Son of Man.²
