Ecclesiastes 8:16-17

International Standard Version

¹⁶ When I dedicated myself to experience wisdom and to observe what is undertaken on earth—even going without sleep day and night— ¹⁷ I saw all of it as the activity of God. Frankly, a human being cannot understand what happens on earth, because however hard a man works to discover it, he will not find out. Despite what he thinks he knows, he will not be able to figure it out.
