“And there followed him a certain young man, having a linen cloth cast about his naked body; and the young men laid hold on him:”
King James Version (KJV)
14:51 A young man - It does not appear, that he was one of Christ's disciples. Probably hearing an unusual noise, he started up out of his bed, not far from the garden, and ran out with only the sheet about him, to see what was the matter. And the young men laid hold on him - Who was only suspected to be Christ's disciple: but could not touch them who really were so.
Mr 14:51,52 And there followed him, etc. Verses 51 and 52 are peculiar to Mark. A certain young man. Some have supposed him to be Mark. This is only conjecture. The incident may have been introduced to show the rudeness of the assailants and to emphasize the escape of all the disciples from so wanton an attack. A linen cloth. A night robe.
