I the Preacher was king over Israel in Jerusalem.

And who knows whether he shall be wise or a fool? Yet he shall have rule over all my labor in which I have labored, and acted wisely under the sun. This is also vanity.

And I turned to cause my heart to despair over all the labor which I did under the sun.

For that which happens to the sons of men also happens to beasts, even one thing happens to them. As this one dies, so that one dies; yea, they all have one breath; so that a man has no advantage over a beast; for all is vanity.

In the day of prosperity be joyful, but in the day of adversity take note that God also has set the one over against the other, to the end that man should find nothing after him.

There is no man who has power over the spirit to keep the spirit; nor power in the day of death; and there is no discharge in that war; nor shall wickedness deliver its owners.

All this I have seen, and I gave my heart to every work that is done under the sun. There is a time in which one man rules over another to his own hurt.
