The chapter opens with a question: who is like the wise, and who knows the interpretation of a thing? A person's wisdom makes his face shine and changes the hardness of his countenance. He then advises obeying the king's command, because of the oath taken before God, and not being hasty to leave his presence or persist in a bad cause, for the king does what he pleases. Where the word of the king is, there is power, and no one can say to him, what are you doing?
The wise heart knows the proper time and way, for there is a time and way for every matter, though the misery of man lies heavy on him. No one knows what is to be, no one has power over the spirit to retain it, or authority over the day of death; there is no discharge in that war, and wickedness will not deliver those who practice it. There is a time when one man rules over another to his hurt.
The Preacher has seen the wicked buried with honor, who had gone in and out of the holy place and were praised in the city where they had done such things. Because the sentence against an evil deed is not executed speedily, the hearts of people are fully set to do evil. Though a sinner does evil a hundred times and prolongs his life, the Preacher knows that it will be well with those who fear God, and that it will not be well with the wicked, who will not prolong his days like a shadow.
Yet there is another vanity on earth: righteous people who get what the deeds of the wicked deserve, and wicked people who get what the deeds of the righteous deserve. So he commends joy: there is nothing better for a person under the sun than to eat, drink and be glad. When he applies his heart to know wisdom and to observe what is done on earth, he sees that no one can find out the work that is done under the sun; even though the wise claims to know it, he cannot find it.
