The chapter opens with a warning about worship: guard your steps when you go to the house of God, for drawing near to listen is better than offering the sacrifice of fools, who do not know that they do evil. Do not be rash with your mouth or let your heart hurry to speak before God, for God is in heaven and you are on earth; therefore let your words be few. Dreams come with much business, and a fool's voice with many words.
Vows must be paid without delay: God has no pleasure in fools, and it is better not to vow than to vow and not pay. Do not let your mouth lead you into sin, or say before the messenger that it was a mistake. The advice sums up as fearing God.
The Preacher then looks at injustice: if you see the poor oppressed, do not be amazed, for one official is watched by a higher one, and over them are yet higher ones. Then he speaks of money: he who loves money will not be satisfied with money, and when goods increase, those who consume them increase. The sleep of a laborer is sweet, but the abundance of the rich will not let him sleep. He describes riches kept to their owner's hurt that are lost in a bad venture, and the man leaves as naked as he came and takes nothing with him.
The chapter ends with what he considers good and fitting: to eat, drink and enjoy his toil during the days of life God gives. God gives each man wealth and power to enjoy it, and for one who lives so, God keeps him occupied with joy of heart, so that he does not dwell much on the days of his life.
