Adam Clarke on Ecclesiastes 7:15

There is a just man that perisheth - This is another objection as if he had said, "I also have had considerable experience; and I have not discovered any marked approbation of the conduct of the righteous, or disapprobation of that of the wicked. On the contrary, I have seen a righteous man perish, while employed in the work of righteousness; and a wicked man prosperous, and even exalted, while living wickedly. The former is indeed a victim to his righteousness, while the life and prosperity of the latter were preserved: hence I conclude, it is not prudent, whatever good there may be in religion, and whatever excellence in wisdom, that men should be overmuch righteous, or over-wise: for why should they by austerity and hard study destroy themselves?" So far the objector.
