Comentário sobre Deuteronômio 31:7

כי אתה תבוא את העם הזה — Translate this as the Targum does: ארי אתה תעול עם עמא הדין, THOU SHALT GO WITH THIS PEOPLE. Moses, by the statement “Thou shall go with this people” (as one of them) said in effect to Joshua: The elders of the generation will be with thee: everything has to be done according to their opinion and their advice. The Holy One, blessed be He, however, said to Joshua, (v. 23) “For thou shalt bring (תביא) the children of Israel into the land which I swore unto them” — thou shalt bring them even against their will; everything depends on you alone: if necessary take a stick and beat them over the head: there can be but one leader for a generation, and not two leaders for a generation (Sanhedrin 8a).

כי אתה תבא, even though I myself have not merited this.

כי אתה תבא את העם הזה, "for you will come with this people, etc." Moses did not say תביא, "you will bring this people," seeing it was G'd who would actually bring the people by destroying their opposition. All Joshua was required to do was to march at the head of the people. While it is true that our sages in Sanhedrin 8 drew our attention to the end of our portion (verse 23) where G'd tells Joshua "you shall bring the children of Israel to the land I have sworn to them," the reason that G'd used the expression תביא was to correct the impression Moses' words had left when he said תבא. According to Rabbi Yochanan Moses meant "you and the elders." G'd objected by saying that there can only be one authoritative spokesman per generation, i.e; dabbar echad ledor. To make this point, G'd said to Joshua "you will bring," instead of "you will come." Now that we have that verse we can interpret the verse in which Moses said "you will come" as a reminder that G'd would do the actual "bringing."
