העושה מקום – that he made a puncture going all the way through in the wall to place there a reed of the weavers.

One who makes a place for a rod, for tongs, or a lamp, the minimum size is whatever is needful, according to the word of Bet Shammai. Bet Hillel says: one handbreadth square. According to Bet Shammai, if one makes a hole in the wall to store a specific item, that hole needs to be large enough to actually store the item for it to allow impurity from one side to the other. Bet Hillel imposes a standard size one handbreadth square. This is the measure we saw above in mishnah one.

ולתשמיש – to hide there his belongings.
