John 3:13
Patriarchal Greek New Testament (1904) · Berean Standard Bible
καὶ οὐδεὶς ἀναβέβηκεν εἰς τὸν οὐρανὸν εἰ μὴ ὁ ἐκ τοῦ οὐρανοῦ καταβάς, ὁ υἱὸς τοῦ ἀνθρώπου ὁ ὢν ἐν τῷ οὐρανῷ.
No one has ascended into heaven except the One who descended from heaven—the Son of Man (note: BYZ and TR include who is in heaven.).
