Parshas Shelach

(The Segulah of Learning Zera Shimshon)

Before the miraglim went into Eretz Yisroel Moshe changed Yehoshua’s name to give him extra shmeira and Divine Assistance. The Zera Shimshon asks why Moshe didn’t change the names of all the miraglim, only his student Hoshea?

The Arizal says that when the miraglim went into Eretz Yisroel they were given the neshamos of the shevatim. Every spy was given the neshama of the progenitor of his shevet. The shevet of Levi did not send a spy because they were not going to be given a nachala in Eretz Yisroel. However, Yehoshua bin Nun, from shevet Ephraim, received the neshama of Levi enabling the spy of shevet Menashe to receive the neshama of Yosef.

Were Yehoshua to sin while he were in Eretz Yisroel, he would leave a blemish on the neshama of shevet Levi. Therefore, Moshe Rabenu changed his name to give him Divine Assistance.
