'Chasing After The Wind' in the Bible

I observed every activity done on earth. My conclusion: all of it is pointless like chasing after the wind.

So I dedicated myself to learn about wisdom and knowledge, and about insanity and foolishness. And I discovered that this is also like chasing after the wind.

Then I examined all of my accomplishments that I had brought about by my own efforts, including the work that I had labored so hard to complete and it was all pointless, like chasing after the wind, and there was nothing to be gained on earth.

So I hated life, because whatever is done on earth causes me trouble it's all pointless, like chasing after the wind.

After all, to the person who is good in God's sight, he gives wisdom, knowledge, and joy, but to the sinner he gives the troublesome task of acquiring and accumulating in order to leave it to someone who is good in the sight of God. This also is pointless and chasing after the wind.

Then I examined all sorts of work, including all kinds of excellent achievements that create envy in others. This also is pointless and chasing after the wind.
