16 When I applied my mind to know wisdomj and to observe the activity that is done on the earth (even though one’s eyes do not close in sleep day or night), 17 I observed all the work of God and concluded that a person is unable to discover the work that is done under the sun. Even though a person labors hard to explore it, he cannot find it;k even if a wise person claims to know it, he is unable to discover it.
