Why should they fear the sword?
Ibn Ezra (28): You pursued me, even though you did not find any evil root in me.
Malbim: You pained me verbally without reason.
What is the meaning of "Ki Chemah Avonos Cherev"?
Rashi: You increase sin that brings to the sword.
Sha'arei Teshuvah 1:10: One who sinned should understand that abandoning Hashem is bitter and evil, and he will be punished!
Malbim: Destruction via the sword comes for verbal affliction. "Kol Almanah v'Yasom Lo Sa'anun; ... v'Haragti Eschem be'Charev."
Why did he say "Lema'an Tede'un Shadun"?
Rashi: You will understand punishments that come on Resha'im!
Rashi based on Tanchuma, Ibn Ezra: The Mesores (how it is written, Shadin) is primary - she'Yesh (that there is) Din in the world. This is like "sha'Kamti Devorah." Malbim - you hold that everything is based on Din and Mishpat. Now you say so with your mouths; you do not know it clearly. You do not fear punishment, and you answer your friend with bitter words. Then, you will know!
