Mark 14:52

καταλιπών. Often used of leaving behind (Mark 12:19; Mark 12:21), or abandoning completely (Mark 10:7; Luke 5:28). In N.T. this compound is far more freq. than λείπω. All these minute details show that, if Mk is not giving his own experiences, he has got information from one who was there. That Mt. and Lk. should omit this incident is natural. That a later editor has inserted it in Mk is very improbable. What would be the object of such insertion? If the young man was Mark, or some one whom he knew very well, we have a reasonable explanation of its presence in this Gospel.
