Commento su Deuteronomio 7:22

פן תרבה עליך חית השדה LEST THE BEASTS OF THE FIELD INCREASE UPON THEE — But is it not a fact that if people perform the will of the Omnipresent they will not have to fear the beasts, as it is said, (Job 5:23) “And the beasts of the field shall be at peace with thee”?! But it states this because it was manifest before Him that they would in future sin.

THOU MAYEST NOT BE ABLE TO CONSUME THEM SPEEDILY. He is assuring them that G-d will destroy them all and send the hornet among them to destroy they that are left and they that hide themselves,⁴¹Verse 20. and thus they will all [ultimately] perish. He states, however, that He will not completely destroy them in war in one day, nor will He drive them out of the Land in one year, lest the Land become desolate, and the beasts of the field multiply against thee.⁴²Exodus 23:29. And He assured them further that those [of the peoples] that are left, will not be the majority, but that G-d shall confound them with a great confusion⁴³Verse 23. and most of them will be destroyed by the hand of Israel. And so he said, He will destroy them, and He will bring them down before thee; so shalt thou drive them out, and make them to perish quickly,⁴⁴Further, 9:3. [meaning] that you will destroy most of them quickly, but they will not be completely vanquished until thou be increased, and inherit the Land.⁴⁵Exodus 23:30.

But is it not true that if they do the will of the Omnipresent, etc. Above in Parshas Mishpatim (Shmos 23:29) I explained why Rashi did not say this reason.

לא מוכל כלומם מהר, “you will not be able to destroy them quickly;” the word תוכל is not to be understood as an inability on your part. It will not be in your interest to do so, as you would create a vacuum of not enough people in the land, that would encourage invasion by free roaming beasts.
