The wisdom of the prudent is to understand his way: but the folly of fools is deceit.

Wisdom excelleth folly, as far as light excelleth darkness.

Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips: / Whose mouth is full of cursing and bitterness: / Their feet are swift to shed blood: / Destruction and misery are in their ways: / And the way of peace have they not known: / There is no fear of God before their eyes.

And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been already done.

And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
