Ecclesiastes 1:18

In much wisdom there is much grief for he who increases knowledge increases pain.

To man he said: 'Respect for Jehovah is wisdom! To stay away from evil is understanding.'

Then I said in my heart: As it happens to the fool, so it will happen to me. Why have I been so wise? Then I said in my heart: This also is vanity.

All his days are sorrow, and his work is full of grief. Even in the night his heart has no rest. This again is vanity.

Do not be righteous over much and do not be wise over much. Why should you destroy yourself?

By these, my son, be admonished! There is no end to publishing many books. Also much study is a weariness of the flesh.

Let no man deceive himself. If any man among you seems to be wise in this age, let him become a fool, that he may be wise.

Who is wise and understanding among you? Let him show by his good conduct that his works are from meekness because of wisdom.

I have seen all the works that are done under the sun. Behold, all is vanity and a striving after wind.

Seeing there is much that increases futility, what outcome is there for man?
