Sforno on Deuteronomy 31:21/ספורנו על דברים ל״א:כ״א

1כי ידעתי את יצרו אשר הוא עושה היום, for I, G’d, know its nature, its character; they do not look forward to taking over the land of the Canaanites in order to serve Me, as I wanted them to and hoped they would do. (compare Psalms 105,44-45 “He gave them the lands of nations; they inherited the wealth of peoples; in order to observe His statutes and His teachings, and observe His laws.”) Instead they look forward to gratify their own cravings as a result of which their excess wealth will be the cause of their decline and corruption, as per 32,15 “Yeshurun waxed fate and kicked, etc.”
