The labor of the foolish wearies every one of them, because he knows not how to go to the city.
All Commentaries on Ecclesiastes 10:15 Go To Ecclesiastes 10
George Leo Haydock
AD 1849

Thus the pagan philosophers knew all but what they ought to have known; (St. Jerome) and many such wise world lings never strive to discover the paths which lead to the city of eternal peace: like him who contemplated the stars, and fell into a ditch. (Calmet)
