Ecclesiastes 8:17
Clementine Vulgate · Berean Standard Bible
Et intellexi quod omnium operum Dei nullam possit homo invenire rationem eorum quæ fiunt sub sole ; et quanto plus laboraverit ad quærendum, tanto minus inveniat : etiam si dixerit sapiens se nosse, non poterit reperire.
I saw every work of God, and that a man is unable to comprehend the work that is done under the sun. Despite his efforts to search it out, he cannot find its meaning; even if the wise man claims to know, he is unable to comprehend.
