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
Didymus the Blind
AD 398
By “town” he does not mean a place but the deed according to the law. The fool does “not even know the way to town.” But the one who says, “Even if we live on earth, our citizenship is in heaven,” “knows the way to the town” in which he is a true citizen. And further: “As we have heard, so we have received in the city of the Lord of hosts, in the city of our God.”
