Sforno on Exodus 23:22/ספורנו על שמות כ״ג:כ״ב

1כי אם שמוע תשמע בקולו...ואיבתי את אויביך, My relationship to you then will not be protective, defensive, i.e. that I need to protect you, but aggressive, by treating your enemies as My enemies. This is the reverse of G’d’s attitude to Nineveh in Jonah 4,11 where G’d asked Jonah: “how can I not relate protectively to a city of over 120.000 people?”
