And David's heart smote him after that he had numbered the people. And David said unto the Lord, I have sinned greatly in that I have done: and now, I beseech thee, O Lord, take away the iniquity of thy servant; for I have done very foolishly.

For the eyes of the Lord run to and fro throughout the whole earth, to shew himself strong in the behalf of them whose heart is perfect toward him. Herein thou hast done foolishly: therefore from henceforth thou shalt have wars.

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.

The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.

O ye simple, understand wisdom: and, ye fools, be ye of an understanding heart.

The wise in heart will receive commandments: but a prating fool shall fall.

He that troubleth his own house shall inherit the wind: and the fool shall be servant to the wise of heart.

A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.

Wisdom resteth in the heart of him that hath understanding: but that which is in the midst of fools is made known.

The lips of the wise disperse knowledge: but the heart of the foolish doeth not so.

The heart of him that hath understanding seeketh knowledge: but the mouth of fools feedeth on foolishness.

Wherefore is there a price in the hand of a fool to get wisdom, seeing he hath no heart to it?

A fool hath no delight in understanding, but that his heart may discover itself.

The foolishness of man perverteth his way: and his heart fretteth against the Lord.

Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.

He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.

Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.

The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.

I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:

A wise man's heart is at his right hand; but a fool's heart at his left.
