In this week's Parsha, Moshe appoints Yehoshua as the next leader and encourages him to be courageous in front of the people, and that he will lead the people into Israel. While this implies that Yehoshua will have authority, when Moshe tells Yehoshua כי אתה תבוא את ,העם הזה אל הארץ )לא:ז( that suggests that Yehoshua will be on a par with the people. This is an apparent contradiction.
Rabbi Dovid Feinstein answers that both of these elements were part of the message that Moshe wanted to give to Yehoshua. Moshe meant to say it is very difficult to be both a man of humility and one of assertivness that would be required by any Jewish public figure, especially in the holy land were God scrutinizes every deed (ארץ אשר עיני ה' א-לוהיך בה). On one hand you must have humility despite your very important position, but on the other hand you must be strong and authoritative to deal with the Jews.
