Why did Moshe say "Bring them", and not 'Bring us'?
Rashi #1 (citing Bava Basra 119b, and the Mechilta): He prophesied that he would not enter Eretz Kena'an. 1
Rashi #2 (according to the Maharshal): It was the current generation (not just Moshe), who would not enter the Land, only their children - despite the fact that the sin of the Meraglim had not yet taken place.
Hadar Zekenim: This is a source in the Torah for Techiyas ha'Mesim. 2
Why does the Torah use the word "Machon" and not 'Makom'?
Rashi (citing the Mechilta) and Targum Yonasan: To teach us that the earthly Beis-ha'Mikdash is exactly opposite Hashem's Throne. 1
Since the word "Machon" can be read 'Mechuvan' (exactly opposite - the dwelling of Hashem [Ibid.]).
Why the double expression "Tevi'emo ve'Sita'eimo"?
Seforno: Bring them to the land and entrench them there permanently - that they should never be exiled from it.
Targum Onkelos and Targum Yonasan: Bring them to the land and encamp them there (settle them down).
What does the Torah mean when it refers to "the Mikdash which Hashem's Hands established"?
Rashi #1 (citing the Mechilta): The fact that the Torah writes "Yadecha" (in the plural), indicates how dear the Beis-ha'Mikdash is in Hashem's Eyes - When He created the world, He created it with only One Hand, 1 yet the Beis-ha'Mikdash that He will build when He will reign Supreme over the entire world 2 He will build with Two Hands.
Rashi #2 (in Sukah, 41a): It hints that the third Beis-ha'Mikdash 3 will descend from Heaven, fully built.
