Ecclesiastes 1:18 For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
Ecclesiastes 2:1 I said in mine heart, Go to now, I will prove thee with mirth, therefore enjoy pleasure: and, behold, this also is vanity.
Ecclesiastes 2:2 I said of laughter, It is mad: and of mirth, What doeth it?
Ecclesiastes 2:15 Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.
Ecclesiastes 2:16 For there is no remembrance of the wise more than of the fool for ever; seeing that which now is in the days to come shall all be forgotten. And how dieth the wise man? as the fool.
Ecclesiastes 2:17 Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit.
Ecclesiastes 2:19 And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have showed myself wise under the sun. This is also vanity.
Ecclesiastes 2:21 For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil.
Ecclesiastes 2:23 For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
Ecclesiastes 2:24 There is nothing better for a man, than that he should eat and drink, and that he should make his soul enjoy good in his labour. This also I saw, that it was from the hand of God.
Ecclesiastes 2:26 For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
Ecclesiastes 3:1 To every thing there is a season, and a time to every purpose under the heaven:
Ecclesiastes 3:2 A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
Ecclesiastes 3:12 I know that there is no good in them, but for a man to rejoice, and to do good in his life.
Ecclesiastes 3:13 And also that every man should eat and drink, and enjoy the good of all his labour, it is the gift of God.
Ecclesiastes 3:15 That which hath been is now; and that which is to be hath already been; and God requireth that which is past.
Ecclesiastes 3:17 I said in mine heart, God shall judge the righteous and the wicked: for there is a time there for every purpose and for every work.
Ecclesiastes 3:19 For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity.
Ecclesiastes 3:22 Wherefore I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion: for who shall bring him to see what shall be after him?
Ecclesiastes 4:3 Yea, better is he than both they, which hath not yet been, who hath not seen the evil work that is done under the sun.
