1. These trees were used for firewood, and their smell would spread throughout all of Eretz Yisrael. However, they were not commonly found after the destruction of the Beis ha'Mikdash.
2. Tana Kama: It is forbidden for a man to go out wearing a sword, bow, shield, club, or spear. If he does so accidentally he must bring a Korban Chatas. Rebbi Eliezer: These are considered "adornments" for a man, and therefore he is permitted to go out with them on Shabbos.
3. Beraisa: There will be no need for weapons, as the verse states, "A nation will not raise its sword to another nation." Shmuel: The days of Mashi'ach will be different from today only in that we will not be in exile under a foreign nation (implying that there will still be violence and a need for weapons).
4. Rebbi Elazar: Hashem makes them succeed, gives them important positions, and lets them acquire and master Torah.
5. Even greater than these two acts is giving him money to invest so that he can take half of the profits.
