עדיות ח׳:ז׳ - עבודה זרה א׳:א׳

הלכה למשה מסיני – For the Holy One, blessed be He showed Moses at Sinai, each generation and its expounders, and showed him that Elijah does not come to make impure or to make pure, to distance or to bring close, to verify [doubtful] families mixed up (i.e., lost to the priesthood as they had been mixed with Israelites beyond traces of genealogical disabilities) beyond recognition; who had been mixed up beyond recognition and who had not been mixed up beyond recognition, but he should leave them and they will be valid in the future to come, for the Halakha is that a family that had mixed up beyond recognition remains mixed up beyond recognition.

אלא לרחק המקורבים בזרוע – for everyone presumes them as invalid, but that they were brought close by force, but a family which had been mixed up beyond recognition on account that it was not known that its defilement was unknown, should be left in its fitness.

בית הצרפה – such is the name of the family.

ורחקה – he announced concerning them that they are invalid.

בן ציון – he was a strong man and a violent person.

ועוד משפחה אחרת היתה שם – that was invalid.

וקרבה בן ציון בזרוע – and he announced concerning them that they are valid to marry with them, and the Tanna/teach of the Mishnah had consideration on the honor of human creations and did not mention the name of the invalid family that Ben Zion drew close forcefully, like he had mentioned the name of the fit/valid family, to teach you how much a person has to be careful not to recount of the denigration of his fellow and to be able to hide degradation. If such is the case with those who are invalid, all the more so regarding those who are valid.

כגון אלו – who validity and invalidity were known but that they were distanced by force and brought closer by force.

לקרב אבל לא לרחק – the valid family that had been distanced by force, he brings close but he does not distance that which had been brought close by force.

שנאמר והשיב לב אבות על בנים – that will be said in the future with the Holy Spirit that this because of the children’s children of this one. And according to the words of Rabbi Shimon, the fathers are the Sages and the children are the students, so that the heart of all of them will be equivalent and dispute will not fall between them.

לפני אידיהם של גוים – [the word אידיהם is] a byname of reproach for their holy days and festivals.

לשאת ולתת – to sell and to purchase. Because they go and praise idolatry on the day of their holidays.

להשאילן – cattle and utensils, things that return as they are.

להלוותם – [to lend them] money but it was not an adornment to the eye, for a loan is given [merely] for the expenditure.

לפורען – when they are collected, they go and give praise to idolatry on the day of their holidays.

מפני שהוא מיצר – on his money which they do not restore to him, and he does not go and give praise [to idolatry].

שמח הוא לאחר זמן – on the morrow [after] his holiday, he goes and gives praise [to idolatry]. But the Halakha is not according to Rabbi Yehuda, and specifically a loan [written in a] document is prohibited to collect from them, but an oral loan is permissible, because he is like saves it from their hands.
