Chapter xxi., which the last two verses of the preceding chapter clearly show to be an Appendix, is equally well attested by all the authorities, while the omission of xx. 31 by the first hand of G is just one of those unaccountable phenomena which make their appearance so frequently in the domain of textual criticism. The same thing is probably to be said of the omission in א of the last verse of chapter xxi. Tischendorf was of opinion that this last verse in א, together with the concluding ornament and subscription, was not by the same hand (A) as had written the Gospel of John, but by another (D) who had acted as corrector, and had written part of the Apocrypha and six leaves of the New Testament. Tregelles, on the other hand, who examined the passage in Tischendorf’s presence, thought the difference was due simply to the scribe having taken a fresh dip of the ink: that at all events the scribe who wrote the Gospel (A) did not intend it to conclude with verse 24, otherwise he would have added a concluding ornament and subscription as in the case of Matthew and Luke. The verse is found in all the other manuscripts and versions with which we are acquainted, and the question with regard to א is interesting only from the fact that a few manuscripts do contain a scholium to the effect that the verse is an addition (προσθήκη) inserted in the margin (ἔξωθεν) by one of the scholars (τινὸς τῶν φιλοπόνων),[274] and afterwards incorporated in the text by another without the knowledge of the former (καταγέντος (?) δὲ ἔσωθεν ἀγνοίᾳ τυχὸν τοῦ πρώτου γραφέως ὑπό τινος τῶν παλαιῶν μέν, οὐκ ἀκριβῶν δέ, καὶ μέρος τῆς τοῦ εὐαγγελίου γραφῆς γενόμενον). This entire note, however, is evidently no more than an inference drawn from the contents of the verse, as the Syriac Commentary of Theodore shows.
