What was the question "ha'Zos Chashavta l'Mishpat"?
1.
Rashi: Do you consider this Mishpat of creations against their Maker, that you said "I am more virtuous than Kel"?!
2.
Malbim: Above, he refuted Iyov's opinion that Hashem handed over conduct to the Ma'arachah, for this would be unjust. If you will say that the Ma'arachah rules over people's choices and decrees what they will do, so they do not deserve reward or punishment, do you think that this justifies Hashem?!
2)
Why did he say "Tzidki me'Kel"?
1.
Rashi, Ibn Ezra: Iyov considers himself more virtuous than Kel.
2.
Malbim: Iyov held, my virtue is decreed from Kel. It is not via choice, so I do not deserve reward.
