신명기 7:7 해설: Rashi, Chizkuni, Da'at Zekenim & Ibn Ezra

לא מרבכם NOT ON ACCOUNT OF YOUR BEING [MORE] NUMEROUS — This is to he understood according to its plain sense. But its Midrashic explanation (taking לא מרבכם in the sense of “not because you are great") is: Because you do not regard yourselves as great when I shower good, upon you, therefore חשק … בכם DID [THE LORD] DELIGHT IN YOU

לא מרובכם מכל העמים, “not because you were more numerous than all the other nations;” the “other” nations referred to here are the seven Canaanite tribes that will be replaced by the Israelites shortly.

לא מרובכם, “not on account of your being so numerous, etc.;” Rash’bam understands this verse as linked to the first verse of the paragraph starting in chapter 6,10. He explains the sequence as follows: G–d does not like you because you are numerous, but He loves you, period. (Love is never motivated by logical considerations based on calculations). Furthermore, He is obligated to make good on the promise He made to your forefathers. If you were to argue then that if He loves us as a father loves his children, why should we burden ourselves with having to observe all His commandments? The answer is that His patience extends until one thousand generations in searching for one that merits His keeping the oath He has given to your forefathers. Whenever such a generation of descendants of these forefathers is prepared to observe the condition of His oath, namely to observe His commandments, all the promises He has made will become effective.
