I the Preacher was king over Israel in Jerusalem.

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

Be not over-righteous, nor show thyself too wise. Why should thou destroy thyself?

There is no man who has power over the spirit to retain the spirit, nor has he power over the day of death. And there is no discharge in war. Neither shall wickedness deliver him who is given to it.

All this I have seen, and applied my heart to every work that is done under the sun. [There is] a time in which one man has power over another to his hurt.
