Not to get too offtopic, but it seems to me that the naked youth/slave in Mark, is just put in, to have a reference to Amos 2:16;

"And the strong one in his heart among the mighty shall run away naked in that day, declares the Lord"

You'll notice just a couple of verses earlier the mentioning of the High Priests slave having his ear cut off by a sword by one of Jesus's followers, very strange thing to do, but it also is a reference to Amos, specifically 3:12, though you need to read the Septuagint version, which unlike the Hebrew mentions a Damascus high priest instead of a couch

"Thus says the Lord, Just as the shepherd draws out from the lion's mouth a couple of legs or a piece of an ear, So will the sons of Israel dwelling in Samaria be drawn out -- With the corner of a bed and a Damascus couch!"(Septuagint has "opposing nation and a Damascus High Priest" instead of the weird bed stuff)

The Greek word used in the Septuagint for "draw out" here is Spao, which can also mean to draw a sword. The Hebrew wouldn't support such an interpretation though. Also the Greek word used for mouth, Stoma, can also mean the edge of a sword, again this only works in Greek not in the Hebrew.

One begins to wonder if in an older version of the gospel, it said Slavish High Priest instead of slave of the High Priest, as this would fit with a possible meaning of Damascus High Priest. Also it is interesting to note that cutting off the right ear of a High Priest would be pretty symbolic, as this is one of the parts of the body along with the right thumb and right bigtoe that are sanctified with blood when someone is made a preist. Being disfigured at all would disqualifiy someone as a High Priest, especially in his sanctified ear. Though it's possible the slave is only meant to be a proxy High Priest, as the young man(or servant) might be a proxy Jesus, escaping death (the Sidon).

And bringing us back to the whole Moses's foot thing, it's clear that the right big toe is smeared with sacrificial blood when someone is made a priest, it's possible this refers back to said Moses event, or maybe some older tradition that both the making of a priest and this circumcision event reference. This is also done in the guilt offering for the leperous, along with the right ear and thumb, so maybe there is a reference in the Moses story to this becoming a type of guilt offering, thus sparing Moses, and then the OP might be correct in that Moses was ill in some way.
