Life for a scribe was hard before computers and typewriters. In this 12th century manuscript, minuscule 2220, (picture below) which resides in the Limonos Monastery in Lesbos, the scribe was copying and writing the Pericope of the Adulteress section of the gospel of John. In the first page you can see the end of John 7:52, ἴδε ὅτι προφήτης ἐκ τῆς Γαλιλαίας οὐκ ἐγήγερται – “see that there is no prophet risen out of Galilee.” Then next he wrote John 8:1, Ἰησοῦς δὲ ἐπορεύθη εἰς τὸ ὄρος τῶν Ἐλαιῶν – “But Jesus went to the Mount of Olives.”

Then, he realized that he had skipped John 7:53.  And so he erased what he had written on the rest of the folio, and started the next folio with John 7:53, και απηλθεν εκαστος εις τον οικον αυτου “and each went to his own home.” (the Antoniades, Hodges and Farstad, Pickering reading.)  The scribe thought, and I would agree, that starting on a new page was preferable to writing over erased text.

Now why did he skip John 7:53 in the first place?  Some other MSS did also, some of them clearly because of homoioteleuton or homoioarcton.  Because 7:53 is each departing to their own home, and 8:1 is Jesus departing to the Mount of Olives.  Scribes skipped from επορευθη to επορευθη, or from απηλθεν to απηλθεν.  In the case of GA 2220 here, he could have had more than one exemplar, and one had επορευθη and another had απηλθεν. Manuscripts 295 and 2411 also skip 7:53, 2411 from επορευθη to επορευθη.
