Rashi on Isaiah
I am sated with the burnt-offerings of rams This is similar to: “Lest he have too much of you and hate you,” (Proverbs 25:18).
Ibn Ezra on Isaiah
To what purpose, etc. Why should I leave you longer in the land ? Is it for the sake of the multitude of your burnt offerings ? I am full, etc. An anthropomorphism ; in reality, He does not want anything; comp. If I were hungry, I would not tell thee, etc. (Ps. 1. 12 ff).
Chomat Anakh on Isaiah
Why do I need your many sacrifices: Because the primary point of a sacrifice is to repent and if you remain rebellious the sacrifice does not help.
