Ecclesiastes is one of the Ketuvim ('Writings') of the Hebrew Bible and part of the wisdom literature of the Christian Old Testament. The title commonly used in English is a Latin transliteration of the Greek translation of the Hebrew word קֹהֶלֶת. An unnamed author introduces "The words of Kohelet, son of David, king in Jerusalem" (1:1) and does not use his own voice again until the final verses
"He hath made everything beautiful in its time."
"All the labour of man is for his mouth, and yet the appetite is not filled."
"All things have I seen in the days of my vanity: there is a just man that perisheth in his righteousness, and there is a wicked man that prolongeth his life in his wickedness."
"Then I saw all that God has done. No one can comprehend what goes on under the sun. Despite all his efforts to search it out, man cannot discover its meaning. Even if a wise man claims he knows, he cannot really comprehend it."
"The sleep of a labouring man is sweet, whether he eat little or much: but the abundance of the rich will not suffer him to sleep."
"I said in my heart: I will go, and abound with delights, and enjoy good things. And I saw that this also was vanity."
