'Ways' in the Bible

All is to no purpose, said the Preacher, all the ways of man are to no purpose.

And I gave my heart to getting knowledge of wisdom, and of the ways of the foolish. And I saw that this again was desire for wind.

And I went again in search of wisdom and of foolish ways. What may the man do who comes after the king? The thing which he has done before.

Then I saw that wisdom is better than foolish ways--as the light is better than the dark.

The wise are troubled by the ways of the cruel, and the giving of money is the destruction of the heart.

Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these things God will bring thee into judgment.
