Mark 14:52

And he left the linen cloth, and fled from them naked.

Jesus went straight from the passover supper to Gethsemane, where He was seized by the mob brought by Judas, and after shameful treatment by the priests and Pharisees and soldiers He was crucified in the afternoon of the same day, which was Friday the fifteenth day of the month, the first day of the feast of unleavened bread, with the morrow after that day, the sixteenth, as the Sabbath and the first of the fifty days reaching to Pentecost. When those involved in His arrest tried to seize him, a young man fled from the scene leaving behind the linen cloth he was wearing, with only that cloth around his body.

The young man is thought to have been Mark, that is John Mark. He lived in Jerusalem, and the reason for the identification is that Mark alone among the evangelists records the incident. He was likely about that youthful age at the time. His identity makes no difference to the account's significance.

The episode belongs to the account of Christ's arrest and rejection and is linked with the change from hollow homage to open violence against Christ, but the verse's detail about the fleeing young man is not explained. In fleeing in that condition from the scene of Christ's passion, he would not have been regarded as respectable by the world.
