Comentario sobre Números 13:16

ויקרא משה להושע וגו׳ AND MOSES CALLED HOSHEA [THE SON OF NUN JEHOSHUA] — By giving him this name יהושע which is a compound of יה and הושע “God may save”, he in effect prayed for him: “May God save you from the evil counsel of the spies” (Sotah 34b).

ויקרא משה להושע בן נון יהושע, the Torah means that this man was known as a man of valour by the name of Hosheah among the members of his tribe. The fact that he has been referred to as “Joshua” already in Numbers 11,28 is because in his capacity as Moses’ personal valet Moses had changed his name in the form of a prayer asking that he be the instrument of his own salvation and that of others.

אלה שמות האנשים, These are the names of the men, etc. Why did the Torah repeat this seeing it had already written: "and these are their names, etc." in verse 4? We may understand this by reference to Sotah 34. Rabbi Yitzchak said: "we have a tradition that the names of the spies recorded in the Torah reflect their deeds;" The name סתור בן מיכאל describes that the man bearing that name contradicted the words of G'd, etc." So far the Talmud on the subject. We have noted that Moses renamed Joshua so as to protect him against the advice of wicked people and we asked why this was necessary. This means that Joshua's name did not reflect the fact that he was wicked. It was necessary to write: "and these are their names" in order to show us why Moses was concerned about the character of these people, i.e. he did not like their names. Whereas I wrote earlier that Moses had the feeling that these men might be wicked because of the word לך, this was not an absolute as the word לך could have other connotations as I have demonstrated. Moses may have been alerted to the potential wickedness of these people when he reflected on their names. Alternatively, Moses did have his suspicions about the enterprise and any men who would be delegated to act as spies; however, had it not been for their names, Moses could not have justified his suspicions.
