Parallel
Ecclesiastes 1:17
Clementine Vulgate · Berean Standard Bible
Dedique cor meum ut scirem prudentiam atque doctrinam, erroresque et stultitiam ; et agnovi quod in his quoque esset labor et afflictio spiritus :
So I set my mind to know wisdom and madness and folly; I learned that this, too, is a pursuit of the wind.
