Eduyos 2:8 - 2:9

סנדל של סיידין – the wooden shoe that they wear on their feat when they are engaged with lime/plaster to protect their feet that they don’t burn in the lime, and if a person with a flux wore it, it would be impure through Levitical uncleanness arising from a someone with a flux’s immediate contact by treading [or leaning against].

ועל שיירי תנור ארבעה – if it was large enough and it became defiled and afterwards broke, he would not be pure until there would not be in its shards a height of four [handbreadths], for shards are susceptible to receiving defilement as if it was whole, until the shard would be less than the height of three [handbreadths]. But a mere oven that is in the Mishnah is made like a large pot which has no rim and when they fasten it with plaster on the ground and the floor of the ground is the bottom of the oven.

שנים מחיפוייו – from the boards that are made for sitting.

שרבי עקיבא מטמא – as he {i.e., Rabbi Akiva) holds that even though it is not appropriate for sitting, it is appropriate to receive pomegranates, and it is impure because it is a receptacle.

וחכמים מטהרין – as they hold because its essential purpose is that it was made for sitting and not as a receptacle, since the purpose for which it had been made was annulled. And it does not defile even because of being a receptacle. And the Halakha is according to the Sages.

האב זוכה לבן וכו' – since it is close that the nature of the son is to be similar to the nature of the father, and beauty, and strength and wisdom and years, a man endows [his son] with them from the beginning of his creation according to his nature, and wealth a person bequeaths to his son. And wisdom that we speak of here, is the straight ingenuity of mind/brightness of mind, which is in a person according to his nature. And years, length of days. And to me it appears that if a person endows them, he will have sons who are pleasant, strong, wise, rich and who live long lives.

ובמספר הדורות לפניו – Sometimes that the Holy One, blessed be He promises that his father will do good for his seed to the third generation or to the fourth generation, and the father endowed to that generation that this particular goodness will come to them.

הוא הקץ – that the Holy One, blessed be He, determined for this matter that it will be for a specific time and for a certain generation, such as (Genesis 15:14,16): “…and they shall be enslaved and oppressed four hundred years…and they shall return here in the fourth generation…,” that the number of generations which is the fourth generation will be end of the four hundred years.
