TSK · Ecclesiastes 6:9

if my step has turned out of the way, if my heart walked after my eyes, if any defilement has stuck to my hands,

"Vanity of vanities," says the Preacher; "Vanity of vanities, all is vanity."

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.

For what has a man of all his labor, and of the striving of his heart, in which he labors under the sun?

Then I saw all the labor and achievement that is the envy of a man's neighbor. This also is vanity and a striving after wind.

a man to whom God gives riches, wealth, and honor, so that he lacks nothing for his soul of all that he desires, yet God gives him no power to eat of it, but an alien eats it. This is vanity, and it is an evil disease.

"For of old time I have broken your yoke, and burst your bonds; and you said, 'I will not serve;' for on every high hill and under every green tree you bowed yourself, playing the prostitute.
