What is a man whose way is hidden?
Rashi: All his good deeds are hidden from the One who rewards; He does not look at them. Devar Eliyahu (26) - even though Hashem testified about Iyov's deeds (1:8), they did not shield him.
Ibn Ezra: It is hidden from him 1 .
I.e. he does not understand why bad things happen to him. (PF)
What is the meaning of "va'Yasech Eloka Ba'ado"?
Rashi: He made a wall in front of him to incarcerate him. This is like "Hineni Sach Es Darkech." Ibn Ezra - this is like one covers a fire.
Devar Eliyahu (26): Hashem made a fence to block his screams from coming in front of Him 1 .
Malbim: He himself lost the path, and Hashem blocks him from seeking it. I.e. he himself is prepared for evils, and the Ma'arachah blocks his choice. He cannot guard and be saved from mishaps decreed on him due to his bad Mazal.
Devar Eliyahu: David said "Doreshei Hashem Lo Yachseru Chol Tov" - I sought Him, and I lack all good! "Einei Hashem El Tzadikim v'Aznav Es Shav'asam" - not only did Hashem not have Hashgachah on me and hear my Tefilah - He made a wall to block my screams!
