Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Καὶ οὐδεὶς ἀναβέβηκεν εἰς τὸν οὐρανόν, 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.).
