Ecclesiastes 6:11

For there are many words which increase futility. What then is the advantage to a man?

Psalm 73:6

Therefore pride is their necklace;
The garment of violence covers them.

Ecclesiastes 1:6-9

Blowing toward the south,
Then turning toward the north,
The wind continues swirling along;
And on its circular courses the wind returns.

Ecclesiastes 1:17-18

And I set my mind to know wisdom and to know madness and folly; I realized that this also is striving after wind.

I explored with my mind how to stimulate my body with wine while my mind was guiding me wisely, and how to take hold of folly, until I could see what good there is for the sons of men to do under heaven the few years of their lives.

Ecclesiastes 3:19

For the fate of the sons of men and the fate of beasts is the same. As one dies so dies the other; indeed, they all have the same breath and there is no advantage for man over beast, for all is vanity.

Ecclesiastes 4:1-4

Then I looked again at all the acts of oppression which were being done under the sun. And behold I saw the tears of the oppressed and that they had no one to comfort them; and on the side of their oppressors was power, but they had no one to comfort them.

Ecclesiastes 4:8

There was a certain man without a dependent, having neither a son nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “And for whom am I laboring and depriving myself of pleasure?” This too is vanity and it is a grievous task.
