Ecclesiastes 6:7

⁵ Moreover he hath not seen the sun, nor known any thing: this hath more rest than the other.

⁶ Yea, though he live a thousand years twice told, yet hath he seen no good: do not all go to one place?

All the labour of man is for his mouth, and yet the appetite is not filled.

⁸ For what hath the wise more than the fool? what hath the poor, that knoweth to walk before the living?

⁹ Better is the sight of the eyes than the wandering of the desire: this is also vanity and vexation of spirit.

Do read the surrounding verses too, because the context often says more than a single verse.
