Why did he say "Gam Hu Li li'Yshu'ah"?
Rashi: When I am complete with Him, also He will be salvation for me. You will not find grace in His eyes.
Malbim: Since I will prove the Emes to Him 1 , He will be salvation to me, and not punish me for this. He does not want to be flattered - "Lo Lefanav Chanef Yavo." He does not want me to be silent and not tell the Emes.
Hashem's knowledge cannot change. He already knows the Emes - why did He not save Iyov until now? Sometimes, Hashem acts only based on Midos that we reveal. Hashem accepted Moshe's Tefilah 'lest Egypt say that You killed Yisrael because You could not overcome the 31 kings', and Rachel's claim 'if I did not envy my Tzarah, surely You should not envy idolatry' (Eichah Rabah Pesichos 24). Hashem already knew this, yet He acted on it only after they said so! (PF)
Does he call them flatterers?
Rashi: Yes - "Lo Dibartem Elai Nechonah."
