What message is inherent in "Veyada'ata ... "?
Ramban: 'Yu will know from Yetzi'as Mitzrayim a. that Hashem ... is the G-d who created Heaven and earth, 1 and b. that He is true to His word, to adhere to the B'ris and the Chesed ... to their descendants just as He adhered to the B'ris that He made when He swore to take their children out of Egypt.'
Rashbam: To know that Hashem will fulfill His promise to the Avos to give them the land, provided their children keep their side of the bargain, 2 for which will wait up to one thousand generations - for one that loves Him and keeps His Mitzvos..
Why does the Torah here give the time-frame of Hashem's reward as one thousand generations, and earlier in the Parshah (Devarim 5:10), as two thousand?
Rashi: Refer to 5:10:1:1.
Targum Onkelos and Targum Yonasan: In spite of the difference in Lashon, both Pesukim translate as 'for thousands of generations'.
What is the difference between "Ohavav" and "Shomrei Mitzvosav"?
