Par 1) The reason that Moshe prayed specifically on Joshua's behalf,“May G-d save you from the counsel of the spies.”
Par 6) The reason that the Mitzvah of Tzitzit is specifically a remembrance for all the Mitzvot
Par 7) Explanation of the verse "I am the L-rd, your G-d, Who took you out of the land of Egypt" in Avodah
Lesson:
1. Moshe davened only for Yehoshua, because as a future leader Yehoshua needs to be devoted to all of his people
6.Tzitzis (to remember all Mitzvos) must be on a talis (fully surrounds a person) signifying that Mitzvos come from a source beyond our comprehension; if we act beyond nature, then HaShem blesses us beyond limitations
