Mark 9:39
All Segments - Min. 124 for some reason is consistently cited as if it doesn't contain the text of Mark 9:39 at all, only appearing along with the other witnesses under —, which is usually for those witnesses "which cannot be related at all... either because of a lacuna or because they are partially or completely illegible." As the transcription of Min. 124 shows, Min. 124 has Mark 9:39 in its entirety without any variant from the majority text (except of course moveable nu and iota adscript). Error present in print edition, pp. 436-437.
Mark 9:40
Similar is true for Mark 9:40, with Min. 124 appearing under — for no particular reason (and agrees with majority text). This in fact continues through Mark 9:41 and through to the end of Mark 9:50. Error present in print edition pp. 438-450.
