Comentario citado sobre Génesis 42:5

AND HE SAID UNTO THEM, YE ARE SPIES. This accusation requires some reason or some plausible explanation, for what did they do that he should so accuse them? People from every country came to him to buy grain, and they were “among those who came,” just as it says, To buy grain among those that came, for the famine was in the land of Canaan.¹⁴⁰Verse 5 here. Perhaps [the reason for the accusation was that] they had the appearance of men of stature and prominence, all of them clothed most gorgeously,¹⁴¹Ezekiel 38:4. whereupon he said to them, “It is not customary for prominent people as you to come to buy food, having as you do many servants.”
It is possible that they were the first ones to come from the land of Canaan. This is the meaning of the verse, And the sons of Israel came to buy grain among those that came, for the famine was in the land of Canaan,¹⁴⁰Verse 5 here. meaning that now they were the first who came from there. So Joseph said to them, “You are spies, since no one has come from the land of Canaan to buy food.” This is the intent of the question, “Where have you come from?”¹⁴²Verse 7 here. which he addressed to them at the outset.

The following Midrash spells out the advice to counter the sin of desecrating the holy Name of G’d by performing public acts of sanctifying that Name (Sifra Emor 9,4-5). The author understands the directive: “I want to be sanctified among the Children of Israel” as a call for someone to risk his life for the sanctification of the Lord’s name. I might have thought that one could have fulfilled this directive by risking his life on behalf of G’d in private; the Torah adds the words “among the Children of Israel,” to teach that this directive is aimed at performing such an act in public. When doing so one must not hope that G’d would save one but must really be prepared to die for the cause. Anyone who publicly risks his life on behalf of G’d’s name hoping thereby to become the beneficiary of a miracle by G’d will not experience such a miracle. If, however, such a person is clearly resigned to the fact that G‘d will not rescue him, a miracle is liable to be performed for him as occurred in the incident of Chananyah, Mishael, and Azaryah, all of whom were defying the threats of Nevuchadnezzar and who chose to become martyrs explaining that they did not do so in order to demonstrate G’d’s power to save them (compare Daniel 3,18). [The author had elaborated on this drawing on a Midrash in Shir Hashirim Rabbah 7,13 describing these martyrs’ previous discussion with the prophet Ezekiel. Ed.] Furthermore, our sages use this verse as proof that matters involving sanctification of G’d’s Name [not necessarily risking one’s life, but prayers such as the Kedushah, Ed.] have to have an audience of at least ten male adults. They draw a comparison between the death of the ten spies in a group described by the Torah as עדה, a “community,” i.e. the minimum number of adult males to which this term can be applied. (Compare Berachot 21). Rabbeinu Yaakov (Tosaphist) already comments on that statement in the Talmud that it is not admissible to derive such halachic rules from an example of the ten spies, i.e. “an ungodly” congregation rather than a “holy congregation.”
The principal message of that discussion in the Talmud is the word בתוך, “amongst.” Clearly, when the word is used here it means “a holy congregation.” When the word appears in connection with Joseph’s ten brothers entering Egypt (Genesis 42,5) it is the Torah’s way of hinting that these brothers at that time were also a holy congregation. [There are many Midrashim proving that the brothers were bent on rescuing Joseph during their trip, certainly a holy task, and one that involved danger to themselves as evident in the story with Benjamin during their second trip. Ed.]
