Ecclesiastes 2:21; Ecclesiastes 6:1; Ecclesiastes 6:3; Ecclesiastes 7:22; Ecclesiastes 7:29; Ecclesiastes 8:6

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.

1 There is an evil which I have seen under the sun, and it is common among men:

3 If a man beget an hundred children, and live many years, so that the days of his years be many, and his soul be not filled with good, and also that he have no burial; I say, that an untimely birth is better than he.

22 For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

29 Lo, this only have I found, that God hath made man upright; but they have sought out many inventions.

6 Because to every purpose there is time and judgment, therefore the misery of man is great upon him.
