Keilim 18:3 - 18:4

אע"פ שמקבלים (even though they contain/retain) – that is to say, even though they did not make an incision while taking the legs, and they have a receptacle as at the outset.

טהורין – that since he took one of their legs off, they were no longer regarded as a vessel, because they do not receive/retain in their manner, but rather lean to one side and are like they are broken.

ר' יוסי מטמא – since no incision had been made in them with the removal of one of their legs. But the Halakah is not according to Rabbi Yossi. But Maimonides had a different reading:"ושאינן מקבלים כדרכן ר' יוסי מטמא." (i.e., instead of saying: “even though that they do not contain something according to their usual fashion. Rabbi Yossi declares ritually impure/unclean,” Maimonides’ version of the text states, “they do not contain something according to their usual fashion.”). But it is something for itself, and this is how he understood it. A chest, a box and a turret which do not contain forty Seah when they sit in the prescribed manner, if one tilts them/causes them to lean, they contain forty Seah, Rabbi Yossi declares them unclean/impure since they don’t contain according to their usual fashion, but the Sages state for since that they do contain/retain, nevertheless, they are considered and containing forty Seah and are pure.

נקליטי המטה (poles of the bed) – two pillars, one from about the head of the bed and one at its foot and they place a staff from one to the other and cast a sheet over it and it becomes a tent.

וחמור (a stand on which the bedstead is placed) – under the frame of the bed, they place a hallow piece of wood that he frame is lying upon, and it is called a חמור/a stand.

וחפוי (a covering) – as for example, a covering that cover the bed and its poles.

טהורים – that is metal which serves the wood.

מלבן (frame) – hollow tablets made to be placed under the legs of the bed so that they do not rot from the moistness of the ground, and they are carried with the bed, therefore they are ritually impure, for they are similar to the bed.

ומלבני בני לוי טהורין – because they would regularly go to Jerusalem and would go from city to city and they don’t bring the beds with them but they do bring the frames, therefore, even though they are fixed in the bottoms of the bed, for since they will ultimately be taken up, they are not considered like the bed.

מלבן שנתנו על לשונות – wood made like a longue that the bed frame is lying upon.

ר' מאיר ור' יהודה מטמאין – that even this is carried with the bed like the frame.

ר' יוסי ור' שמעון מטהרין – that it is not carried with the bed all that much. And the Halakha is according to Rabbi Yossi and Rabbi Shimon.

שמלבני בני לוי טהורין – for even though that they are fixed in the legs of the bed, since that ultimately they are taken off, they are ritually pure, these tongues are also sometimes removed from the frames of the bed, and are not considered like the bed.
