Ecclesiastes 3:10-12 Modern English Version (MEV)
10 I have seen the task that God has given to sons of men to be concerned with. 11 He has made everything beautiful in its appropriate time. He has also put obscurity in their hearts[a] so that no one comes to know the work that God has done from the beginning to the end. 12 I experienced that there is nothing better for them than to be glad and do good in their life.
