For thou hast hid their heart from understanding - That is, the heart of his professed friends. Job says that they were blind and perverse, and indisposed to render him justice; and he therefore pleads that he may carry his cause directly before God. He attributes their want of understanding to the agency of God in accordance with the doctrine which prevailed in early times, and which is so often expressed in the Scriptures, that God is the source of light and truth, and that when people are blinded it is in accordance with his wise purposes; see Isaiah 6:9-10. It is “because” they were thus blind and perverse, that he asks the privilege of carrying the cause at once up to God - and who could blame him for such a desire?
Therefore thou shalt not exalt them - By the honor of deciding a case like this, or by the reputation of wisdom. The name of sage or “wise” man was among the most valued in those times; but Job says that that would not be awarded to his friends. God would not exalt or honor people thus devoid of wisdom.
