What is the meaning of "Ede'ah Milim Ya'aneni"?
1.
Rashi (from Tanchuma Yashan Bereishis 13): Even if He would block me from speaking in front of Him, perhaps He would speak with me and I would know words that He answers me.
2.
Malbim: I should be able to understand the words that He speaks and the matter that He tells me. Now I cannot judge against Him - He does not answer me.
2)
Why does he not understand?
1.
Malbim: Even if He would answer me, He speaks in another language that I do not understand. Also, the matter is deep and hidden from man's intellect.
