און איר זאָלט ניט גײן אין די אײַנפירן פֿון דעם פֿאָלק װאָס איך פֿאַרטרײַב פֿון פֿאַר אײַך; װאָרום דאָס אַלץ האָבן זײ געטאָן, און איך האָב מיך פֿאַרעקלט מיט זײ.
Rashi
קוץ — ואקץ signifies loathsomeness. Similar is: (Genesis 27:46) "I am sick (קצתי) of my life”, like a man who is disgusted with his food (Sifra, Kedoshim, Chapter 12 16).
Chizkuni
ולא תלכו בחקות הגוי, “you must not adopt the statutes of gentile nations.” The reason why this too has been repeated here is so that you could not claim that these statutes are only the ones that apply to the Israelites as a community, but not to statutes that apply to them as individuals.
Ibn Ezra
I abhorred them An anthropomorphism, as in “His soul was disgusted” [Judges 10:16].
