What is the meaning of "Ki Ye'alef Avonecha Ficha"?
Rashi: Your Yetzer ha'Ra teaches your mouth to speak such words!
Ibn Ezra: Your mouth teaches a person and informs him of your sin.
Malbim: Your sin taught your mouth - your speech shows that you already considered this heresy many times. Your sin trained your mouth to speak quickly!
Why did he say "v'Sivchar Leshon Arumim"?
Rashi: You should have chosen to speak like the wise!
Ramban: You speak deceitfully, like one who wants to understand Rasha v'Tov Lo, Tzadik v'Ra Lo. You cannot fool us - your mouth revealed that you do not believe in Elokim!
Malbim: You speak philosophically - this shows that the words did not fall from your mouth by chance amidst great pain and afflictions, rather, after much investigation.
