Job 35:15 - Matthew Poole's English Annotations on the Holy Bible

Because it is not so, i.e. because Job doth not acknowledge God's justice and his own sins, and wait upon God in his way for mercy, according to the last advice given to him, Job 35:14. He, to wit, God, to whom this great work of visiting is ascribed every where in Scripture. Hath visited in his anger, i.e. hath laid grievous afflictions upon him; all which is too little to bring Job to compliance with God. He knoweth it not; Job is not sufficiently sensible of it, so as to be humbled under God's hand. In great extremity; or, though (which particle is sometimes understood, of which examples have been before) in great extremity, or abundance, to wit, of afflictions. Though Job hath hitherto been and still is exercised with very sore calamities, yet they have not brought Job to the knowledge of God and of himself. But this verse is and may be rendered thus, And now know that his (i.e. God's) anger hath visited thee little or nothing, (to wit, in comparison of what thou hast deserved and mightest reasonably expect,) neither hath he known (i.e. judged or punished, as this word is used, Proverbs 10:9, and elsewhere) thee in or according to (as the prefix beth is sometimes used) the great abundance, to wit, of thy sins. And therefore thy complaints against God are very unrighteous and unreasonable.
