Matthew Poole and continuators on Ecclesiastes 10:15

15 The labour of the foolish wearieth every one of them , because he knoweth not how to go to the city .

Fools discover their folly, as by their words, of which he hath hitherto spoken, so also by their actions, and by their endless and fruitless endeavours after things which are too high and hard for them.

For he is ignorant of those things which are most easie and most necessary for him, as of the way to the great City whither he is going, or obliged by his business to go, which being a great and beaten road, is known even to Children and natural fools.
