Sforno on Leviticus 26:16/ספורנו על ויקרא כ״ו:ט״ז

1אף אני אעשה זאת לכם; I will do what you had meant to do when you broke the covenant, so that I on My part will also free from the obligations it imposed on Me. My undertaking had been to be your G’d as a direct protector instead of protecting them through intermediaries.

2והפקדתי עליכם בהלה, I will appoint over you “officials” of alarm, something along the line of Ezekiel 9,5 “then to these He said in my hearing: ‘follow him through the city and strike. Let your eyes neither spare nor show mercy.’”

3ואכלוהו איביכם. We have evidence of this prediction coming true repeatedly in the period of the Judges when such nations as Amalek, Midian, Aram, and others invaded the Land of Israel. (Judges 6,3)
